The babies have, so far, acclimated well into the flock. All though I would say they are still on the fringe. They come out of the coop into the yard later in the day, never early, and if they have full run of the coop, they are everywhere, checking everything out. However, if the big birds are in the coop they pretty much stay in their safety cage, only coming out after everyone has roosted.
This is where I found them yesterday. All the other chickens were out in the yard. See that one on the far left, yeah, pretty sure that's a roo.
All though, in this picture he sure looks like a Dolly!
