I have sort of a hodge-podge flock. A barred rock, a brown sexlink, 2 leghorns and a rescued new england red. I'm getting about 4 eggs a day. I had the red all alone.. before I got the others and I know she lays giant brown eggs. Now i'm getting a small white egg, a med cream colored egg and a medium white egg. But everytime I get a med white egg it's broken. None of the other ones are ever cracked or broken but I have never gotten the med white egg unbroken. i have to throw it out everytime. What's going on? I cant tell if it's getting pecked or just breaking in the laying process. Is it possible that it's coming out defective?
