Here are my chickies, they will be around 3 weeks today. We are in OK and the temps have been in the 80s but for the next few days we will have lows in the high 40's at night. We had been planning to move the babies into the coop as they are getting pretty crowded in the brooder... are they feathered enough? I am going to put a heat lamp out there. The coop is a repurposed 8 x 10 shed.
