These babies are our first chickens. I have done lots of research, but haven't found anything that can help me figure out how old they are. The "chicken lady" at the feed store where we purchased the chicks was out on vacation and the girl who helped us didn't know their age. She did say that the larger BR (in the first pic)was from an older group of chicks. Anyone able to help me out with this? I would also love it if someone could tell me what breed/mix the buff colored chick is. Thanks so much! Heather *Sorry for the big pics. Photobucket has been giving me fits this morning.
