So I've got these 4 chicks that have lost their mother this week. They are 5-6 weeks old and in a cage of their own. They roost on a board at night. One of them tries every evening to roost on the backs of his fellow chicks. They sit on the board, he sits on top of either of them. They wriggle and try to shake him off. Why does he do that? I suspect by his comb that he's a little roo, but isn' t that a bit early? And he does it only at roosting time in the evening.
