Hello everyone, i'm new here and to having chickens and have a question! I got 6 chicks about 2 weeks ago from tractor supply and they said they didn't really know how old they were, but i'm guessing they are between 3 and 4 weeks old. i was wondering if it would be okay to put them outside in the coop i built if i put the heat light in it? i have all the doors closed on it because i haven't built the run yet, which i will build this weekend. so my question is this, if they are old enough to go out in the coop with a light and the run blocked off, do i need to cut a hole in the side of the coop and put hardware cloth over it for some air?
