I think we've reached the point where the girls need to move outside! They are 4 weeks old today and they are getting too big and too active for the brooder! All but one of them have a good amount of feathers, with some down feathers still left - mostly around the head. They are all close to pigeon size now. We were going to move them outside this morning, but the temps tonight might dip into high 50's. The nightly temps the rest of the week should stay in the mid to high 60s. We are going to move the heat lamp out into the coop just in case, but we were nervous about the 50s....
