Ok I think my hen gets mad at me.... Does anyone know why she pecks a hole in the little end of her egg ?? I would say out of 5 or so eggs a week she lays she pecks about 4, doesn't eat them or break them open just a little peck hole.... it's like she's saying ha ha now you can't have it.... Does anyone know why , and what can I do to stop it ???? THANKS !!!!
