I have my first chicks and they are 10 weeks old. I am posting both because I'm wondering and think it's so cute...they all still peep! I love it that they are so big and still make peeping noises. There is only one girl who makes anything resembling a cluck, the roosters have not even tried those first crows that I have read about on BYC. So, just wondering, when do they usually start sounding like chickens?
