So I moved my 8 week old chicks outside to their coop 3 days ago. It has been no cooler than about 65 at night and 85-90 during the day. We're in for a cold snap tonight. It's supposed to get down to 45. I am soooo tempted to just throw the brooder back together and bring them in. Are they going to be alright? Should I drag out the heat lamp? Ugh, I feel like a new mother. Any advice/support would be greatly appreciated.
