I've got an 8-week old Wheaten Penedesenca pullet with two 5-week old Ameraucana....chicks. Not sure on their genders yet, will post pics & ask opinions when they're a little older. Anyway, last night, I peeked in their little pen, and I saw the cutest thing - the WP squatting down, had her wing over the top of one of the chicks, and the other chick was on her back; all half asleep. One of the chicks was making a real cute "trilling" noise - that's the best way I can think to describe it. None of them were standing; all sitting and close to sleep. I thought it was a happy sound, relaxing or something, but I understand it MAY be an indication that whoever's making it, could be a roo. Anyone have insight into this cute little sound?
