I am just so excited I found this site/forum. I wish I had found it sooner! I have 7 week old chicks I just put out in their coop yesterday. I ordered them from Mypetchicken.com. I ordered 25 hens in a variety type pack. I have no idea what breeds they are. But I love them all! We only lost 3 and that was in the first few days. they have always gotten along just fine, no fighting ect. I have been thrilled! Yesterday I put them out in their new coop (its very large) and right away the chickens started to kinda fight each other. They would puff up their necks and bounce their chests against one another. Some would flap their wings or use their feet against the other one. Each 'challenge' or 'fight' only lasted seconds. But it seems most of them took turns doing this to each other. After about 15 minutes though, they calmed down and it was back to normal. I went out this morning and it is all calm and they are all getting along and I haven't seen that behavior toward eachother at all.. I sat out there for about an hour this morning and no fighting, they only did it for the first few minutes yesterday when I put them out in the new coop. I was very worried yesterday though thinking maybe I got roosters and not hens from the place I ordered them from??? These are my first chickens. So I don't know how I could be able to tell a rooster from a hen? So my question is, do hens fight each other to? Do I need to worry I might have roosters? Thank you so much!! Oh and if anyone could tell me, what age do hens start laying??
