Hi there, I have a 48"x32" space for my chicks. How many do you think I could fit comfortably in there towards the end of them being in the brooder once they're feathered and about ready to go into the coop? Basically, I'm not concerned about fitting as many as I can, as this would be my first bunch of chicks and I'm only looking for a few hens. But I would like to know your opinions. Thanks!
