I moved my almost 4 week old mostly feathered chicks outside today-I planned for them just to be out for a little bit, but their pen is built so that I can't get ahold of them until they go inside the coop. I put a heat lamp in there and a couple of chicks climbed the ramp to get to it. All of them are huddled now outside in a corner and a few are peeping loudly(assume they are cold). Will they go up to the light, or am I going to have to tear the whole run apart to fetch them?!
