Ok so first of all I'm very new at this but reading everything from you all has been a big help. But here is something I would like to hear your opinions about. I got some of my chicks from the co-op and some from tsc. Well 4 from tsc are a little older than the others and are beginning to get feathers around their chests and shoulders. How old do ya reckon they are and how long do you think before they need to go out? Thanks a ton.
