I have 9 chicks that are just over 7 weeks old living in my basement. They need more space and I need less smell in the house. My question is - I made them a bigger brooder in the unheated garage out of a cardboard watermelon box. So far the temp in there is up to 55 degrees using a 250 watt red heat lamp. Do you think they will be OK moving from my basement to that? They have had no heat in the basement since they were like 3 weeks old and it is probably 65 down here. There are three d'uccle roos, 5 silkies and a frizzle cochin that I was going to move.
