I know this question has been asked many times before but I haven't found an answer specific to my situation. Apologies in advance. I don't know how old my chicks are - got them at the feed store two weeks ago. They are starting to fly up out of the brooder, though (they are clever: first onto the top of the feeder, then out!). I keep the chicken wire top on and that keeps them in, but the brooder is seeming a bit cramped and there are only four of them. I don't have any older chickens, the coop is in the garage with a run that leads to the outside and is covered, and I live in Oregon, where in July the temps never get below 55 (and usually not below 60). If I were to put the brooder lamp in with them, do you think they would be ok in their coop, or should I wait? I don't want to rush them, but they seem so energetic and confined in there.
