We have a loner chicken named Penguin. She is an Ameraucana, and she always perfers to hang out by herself. She even expects to have her own special treat pile if we give out treats! I always used to feel sorry for her when she was a young chick, because she was obviously at the bottom of the pecking order, but now I kind of think she prefers it there because it means that none of the other birds want to be around her. Even the rooster doesn't seem to want to mount her or bring her bugs that he finds in the spring--she gets her own. I thought that when the winter came, she might get over her preference to roost alone at night, and prefer to body heat of the other hens. But there she is, even on sub-zero nights, fluffed-up all alone, while the other chickens huddle together on their own perch keeping warm. She does everything alone, and seems to be very happy. She has a great personality, and loves to greet her humans and dog at the fence when we go out into the backyard. I guess she's just a born loner! Does anyone else have a loner chicken?
