Oh , to be a position hen and regularly raise eggs … It is a natural but passably deadening thing !   Some chickens lay eggs day by day , some once per week or less , and some in between . Did you know that shell are made up of almost pure calcium ? Yup , they surely are – nearly 100 % Ca carbonate crystals !

The biological appendage of make and lay an egg slightly deplete the hen of her calcium reserves . Without a way to fill again the calcium used , serious and even life - threatening precondition may result!For example , if a hen is not provided passable gratis - choice calcium in her dieting , and thus can not right spring eggshells , she may lay soft - shell eggs , become perilously egg - bound , or even have an egg break inside of her . Those shivery scenarios merit a post of their own ( which I plan to indite presently ! ) but for now , get ’s focus onproactive bar .

There are a duet of ways you may cater atomic number 20 to your laying chickens to keep them as healthy as potential . Two pop choice are to course chickens shell and/or oyster shells . Let ’s discourse those option , along with somebest practicesand thing to avoid .

Should I offer chickens crushed eggshells or oyster shells?

Wait … Back up . I can feed my chickens eggshells?Isn’t that like , cannibalism or something ?   No ! It surely is not . It ’s actually very common for chicken keeper to feed crush eggshell back to their chickens . what is more , chickens are known to eat on their own eggs and shells out in nature too . We wish to mostlyoffer our girls eggshell – and that is what they happen to prefer as well ! I ’ll explain why as we go .

Crushed orflaked oyster shellsare also useable to bribe , specifically for this purpose . When we first part raising chickens , we corrupt a travelling bag of huitre shells for our girls . infer what?They would n’t meet them . Apparently , thelarge severely rocksof huitre shells for calcium were all unappetizing to them . On the other manus , they absolutely love to gobble down crushed eggshells !   I have learn similar stories from many volaille - lady ( or man ) friend .

To choose oyster shells or egg shells as a calcium supplement is a personal determination – but one that your chickens may help resolve for you !

Cost and Supply

Here is the deal : Eggshells are free!Why not make in force use of a “ waste ” product , and not need to pass any money doing so ? They seem to be what many chickens prefer to eat anyway . It go like a no - brainer , right?However , there is definitely a time and place where using oyster shells instead can come in handy .

One such instance when having oyster shells on hand may be necessary iswhen you ’re running short on eggshell . Say you ’re sell egg , or regularly pass away dozens to Quaker . In that case , you belike will not have enough free scale left to supply your raft enough Ca . orchis - set chickens can not go more than a few days without that extra calcium source , so you will need to supplement ! ( Unless you ask your Friend to keep the shells and return them to you , which we have altogether done . )

Thankfully , we recently found a thinner , flaky , tasty oyster shell than those old “ oyster rocks ” that our young lady dislike so much in the past times – one that they will actually eat!Now , we mixthese huitre shellswith their eggshells to bolster our supply when postulate . Even when we are n’t “ curt ” , we add a little huitre shell with their eggshellson social occasion , simply to keep them wonted to eating them .

How & When to Provide Chickens Calcium

Whether you ’re providing supplementary atomic number 20 via eggshells , oyster shell , or both , there are a few crucial health retainer you need to get it on about !

Age

First things first . Gallus gallus should not be provided additional calcium until they ’ve “ come into lay ” – that is , have begun to lay eggs , or are damn near quick to . Introducing supernumerary calcium prematurely can actually harm young chickens and induce kidney terms . We generally put out eggshells after one of our young chickens begins to lay , even if the others that are the same historic period have n’t get down yet . You could also begin to offer Ca just before they start to lay . Find outwhen do chickens start laying eggs here , include 5 preindication to watch for !

As they mature , chickens need slightly less protein and a piece more Ca . If you pay aid to their labels , you ’ll see this reflected in the content of their various stage of feed : chick or “ starter ” , grower , and layer feeds . Their food is formulated and adjust accordingly . Thus , laying biddy should always be fed a “ bed ” provender . If you are curious , we fertilize our chickensthis constitutive layer feed by Scratch and Peck .

Let me decide!

Second , your deal supplementalcalcium source should always be offered as “ devoid choice ” . This means that it should NOT be mixed into their solid food or hidden in treats . Put the crushed eggshells or oyster shell in a freestanding dish , and keep it stocked and available at all time .

As shown below , we provide shells in asmall hanging dishthat easily attach to fencing material – with one in the yard , and one in their run . They graze on it as they please . Listening to their bodies , poulet somehow know when they are in penury or not ! Mixing an extra Ca root into their feed sort of tricks them into eating it , and can lead to “ o.d. ” and wellness issues similar to if they take too much too vernal .

How to Prepare Eggshells for Chickens

snap an egg , electrocute it up , and toss the eggshell out in the yard for the birds … right?Not quite ! Some kinsfolk may do it that way , but we prefer to take a couple extra ( but easy ! ) steps before give the shells to our chicken . How you prefer to prepare your eggshells is ultimately up to you , but allow me share how we do it .

Before feeding them back to the chickens , we opt tobake and jam their eggshellsfirst .

Why bake the shell first?Because bake the casing makes them safer for the chickens , bykilling any possible bacterialurking on them with heat . This is especially important if they were sitting around for a while after being cracked undecided .

Two chickens, one black and white and one brown and orange, are standing in front of a wire fence. Attached to the wire fence is small metal bowl with hooks, full of crushed eggshells for calcium. Some are spilled on the dirt below too. Succulent plants frame the image in the foreground.

Drying the shells in the oven also dries out the tissue layer , and make the shellsmucheasier to crush . Finally , it alsochanges the odor and flavorof the eggs . By doing so , it reduces the likelihood of your poulet associating the shells with the eggs that they lay – and developing a taste for them ! It render them distinct and unrecognisable as egg . orchis - feeding is an obnoxious and unmanageable habit to break once they start!Trust me … Ugh .

Baking, crushing, & storing eggshells

As we use eggs , wesave up the shellsin a container in the back of the electric refrigerator . continue them refrigerated reduces bacterial growth , so we do n’t get at rinsing them after cracking before computer memory . Then every month or two , we prepare a prominent batch . await to bake many at once makes it much less of a hassle or frequent chore !

circulate the shells on a cookie sheet or bake pan . They can get a petty stuck and difficult to clean , so we use a cheap pan from a thrift memory , dedicated for eggshells . Bake the shells on 300’F for 5 to 10 minutes . We generally do around 5 arcminute if they ’re already on the juiceless side , or for a modest pot , and a bit longer for a large amount or when they ’re still quite stiff . Remove from the oven , and allow to cool .

Next , vanquish the shellsto a consistence of your hen liking . Some folks grind them up very small , almost into a powder . We ’ve retrieve our girls like to peck at slightly larger pieces , about the size of raw oatmeal flake .

To physically crush the shells , notice whatever method works for you . It could be done right on the pan , in a jarful , bowl , coffee poor boy , food processor … Scheol , some people even apply a mortar and stamp ! We typically bemuse all the parched shells in a designated , re - used , large ziplock udder and then crush the contents with arolling pinor our hands . A zero - waste matter , charge card - free option is to do the same in an one-time pillow casing or cloth udder – which is what I plan to try next batch !

last , we stash away the crushed eggshells in jar in the fridge . As needed , wereplenish their little bag outdoors – so that they ’re never without .

It is as simple as that.

Is n’t it crazy to think that such a lowly act plays such asignificantrole in keep on your chicken intelligent ? Providing a little calcium can save their lives!Literally .

If you ’re reading this , I adopt that you have ( or will soon have ) chickens . But if you do n’t , you could still salve your eggshell ! break down and add them to your compost pile , worm bin , or straight into yourgardensoil as a natural amendment . The special Ca is prize there too !
