I brought this up some time ago and try as I can there is no way I can tell which of the 26 hens we have will eat the layed egg...or at least crack and eat the insides before I pick them up. Oh I have caught them, but If I don't check every half hour from morning to mid afternoon they will get a few. Someone told me there might be product egg shaped to put in the nest that when they were bit into would be a bitter taste to train them to stop. For some reason that doesn't sound right. I make sure they have plenty of crushed oystrer shells but it doesn't stop them. What do you folks do?
