I'm glad some of you are using your coop as a brooder. That's what I did when my chicks were almost 3 wks old. It just didn't make sense to keep changing up to larger brooders. Especially since the weather has been unseasonably warm...in the 90's most days. We only used the heat lamp at night when the coop cooled down. The problem I'm having though is that contrary to what I thought, my chicks don't have enough sense to come in from the run as night falls. I've had to pick them up and put them in the coop and they complain and try to get back out until I close them in. I've only let hem out in the run freely the past two days.Last night I went out at 9pm and they were huddled together in the corner of the run near the chicken door. Will they eventually learn to go into the coop on their own? Any ideas on how to teach them that's where they sleep?
