I am soooo sad. I have 4 chickens that grew up together and up until last night wouldn't go anywhere without each other. I have two Australopes and two Silkes. One of the silkies turned out to be male, but he's not the problem. They are about 24 weeks old and the two of the ladies are laying, the silkie and the Australope. My other female is not only not laying, but she is keeping the girl silkie from getting into the coop and has started pecking at the other. What is going on?
