In order to form strong egg shells, chickens require a certain amount of calcium in their diet. Most of an egg shell is made up of calcium. High production hybrid hens are capable of producing a staggering number of eggs in a year on very little feed (known commercially as the ‘conversion ratio’) so they are more likely to need the extra calcium to be able to produce the right number of eggs of sufficient quality.
Oyster Grit available in 25kg bags.
