I have a Golden Sebright Bantam and I read that they are not supposed to be broody but she has been displaying some weird behavior. She resides with a Rhode Island Red who lays every day. My Bantam does not lay every day and has not for the last two days. She has taken to sitting on the Rhode Island Reds egg each day and seems to get very upset if I go near her. She will not get off the egg and its not even hers!! She doesn't even come out to eat or drink just wants to sit there all day. Is this normal? Shall I let her sit on the egg or take it away from her?
