I have 8 full grown hens and 2 babies about 8 weeks old. We have done introductions and they are all great together when they are out free ranging during the day in our yard (fully fenced and safe for the babies). We haven't had any pecking on the littles and nobody seems to pay any attention to them. I still bring them inside to sleep because I would hate to have anything happen overnight. I am kinda done having chickens in my house though. When and how should I start having them sleep out with the big girls??
