Inside the nest box , four browneggswait to be amass . Three of the four are nestled in wood shavings , the fourth reckon like a wet plenty ; the egg ’s insides are visible along with a flimsy film of shell . Laying an bollock or two with a flimsy shell might occur as day get shorter in the fall and winter and young layers reach flush yield . However , if you keep to see thinly - shell eggs , you take to examine the variables affecting a hen ’s health .
Understand Shell StructureAn shell ’s main ingredients are calcium carbonate , Mg carbonate and atomic number 20 phosphate , as well as soluble and indissoluble protein . Ninety - five percent of the eggshell is calcium carbonate — the same sturdy substance that makes up coral , limestone and seashells .
It take 2 g of calcium carbonate for a backyard biddy to form each orchis . To come up with the necessary calcium each day , the biddy borrows it straight off from its own bones . Leg , wing and rib bones lend the calcium without impacting its wellness .
An eggshell has an inner and out tissue layer , a mammillary layer , a spongy level and a shield stratum that is finished with Ca carbonate , says Joe Regenstein , prof of food science at Cornell University .
“ The porous nature of the nut allows for gas transport between the interior and exterior of the ball , ” he say .
The shell can relinquish C dioxide build - up inside while soak up atmospheric air into the interior . At hatching , the air travel cell inside the nut is 15 per centum of the testis ’s volume , supply the first air the biddy will catch one’s breath .
Regenstein explain that if the hen is n’t repose a structurally sound eggshell , its hormones , physiology and nutrition might not be work expeditiously to support the egg - development procedure . If a hen is n’t consuming enough calcium in its for eggshell production , it may involve more nutritionary support .
Find Nutritional BalanceWhen a chick grows toegg - laying matureness , it ’s time to switch from a agriculturalist feed to a layer feed . Layer feed has a higher layer of atomic number 20 in it than a grower provender .
Most commercial feeds are going to be accomplished , says Andrew Brake , co - possessor of Agrarian Urban Homestead and Supply , a retail gardening store in Indianapolis . However , just like some homo need more or less of sure nutrient in their diets , so do some chickens . Some hens wo n’t get enough Ca from layer feed and they will need a appurtenance to support goodish egg yield .
Many people flow dissimilar types of greens — Indian mustard commons , Brassica rapa greens , asparagus , okra , mushrooms , green bean plant and summer squash — and add in things such as buttermilk or clabbered Milk River .
chicken will also eat banana , Citrullus vulgaris , strawberriesandtomatoes . Because these birds like to feed , they will run through virtually anything . Free - chain hens will also feed grass , insects , earthworms , grubs and whatever else they may grave up from flowerbeds and lawns . This variety can be good , but it ’s important to keep an eye on the consumption of the balanced provender dieting . Just like some the great unwashed who might opt to eat too many Hershey ’s kiss , hens will pick out treats over the balanced diet provided by a feed .
fertilise nutritive treat and Supplements
Oyster ShellThe traditional calcium supplement for a layer dieting is oyster shell . huitre shells face a bit like sand and are mash to the point that hens do n’t have to knead to eat them . Tom Tabler , an extension poultry professor at Mississippi State University , recommend place out a separate dish of humbled huitre shell , which the chickens will eat it when they need Ca .
“ If it ’s available to them , the hens will wipe out enough to keep their own shells hard , ” he says .
Rock PhosphateTabler notes that while daystar is n’t as cock-a-hoop a deal as Ca , it ’s also important and interrelated . Hens need a proportion of 1 part morning star to 2 contribution calcium . you’re able to purchase defluorinated rock phosphate in grit or pulverization form and put it out in a bowl for free - alimentation just as you would oyster shell .
Crushed EggshellsCrushed eggshells can also be feed back to hen in a freestanding trough . Tabler recommends baking the eggshells for 30 minutes at 350 degrees F to draw in out the wet and toss off any lingering bacteria . Once the moisture is gone , the carapace will be easy to break down .
The jeopardy of feed in eggshells back to the slew is that they may become egg eaters , breaking into and ingest their own egg before they can be garner . By break the old shells into minor unrecognisable bits discourages this behavior .
All of those option — from which complete provender to costless - feed huitre and phosphorus to custom scratch and wholesome treats — help backyard chickens lie hefty eggs . At the same time , these practices give the backyard chicken - keeper the chance to make their own custom egg supporting their nutrition while enjoy the antics of their hens .
