Hi, I have three 2 year old hens - a Barred Rock and two Buff Orpingtons. I recently got 3 new birds - a Speckled Sussex and two Silver Laced Wyandottes. With the first chickens, I think I moved them out at about 8 weeks old. They were feathered out, and it was warm at night, since it was August. I was thinking of moving the new chicks out when they were 8 weeks old, which is next week. However, I read something else on here that if they are much smaller than the other chickens, it could be bad. I intended to keep them in their dog crate and put them in the run for a few days before trying to let them be loose in there without protection. Should I wait? My concern is that they are getting awful big for the dog crate, so I may need something else to keep them in if I need to put it off for a while. Thanks!
