Well, after chasing escaped chickens around my house two days in a row, I moved the brooder outside. They are six weeks old, and all feathered except their bums. They are still in the brooder (we are finishing the coop this weekend) and on the screened in porch. It is about 80-85 during the day, and last night it got down to 65. I put an old blanket over part of the brooder last night to help hold heat in (since the coop will hold heat too) and they are all great this morning. I feel like a bad mom for kicking them out, but chasing chickens in the house and a toddler was not working. lol. Anyone else put their babies out recently?
