Mine are brooded in the coop from day one. Last year they came in late April with lows in the mid to high 20's.That’s rather young to be moving into a coop.
I have used heat lamps until last year. I finally bit the bullet and tried the "Mama Heating Pad" method. I won't go back to heat lamps. The chicks I raised last year were the happiest, healthiest chicks I've ever had. Here's a link to the thread if you're interested (it's super long - I'd suggest starting from the beginning and glean as much information as you can, then read at your leisure):Thanks! I've been going back and forth over the heat lamp thing. I can hang it from the ceiling, so it is well away from the shavings. The temp out there last night was 34 (with the door wide open. I can close it at night. I'm worried the heat plate is no longer big enough for them all to get under. Maybe if I drape of towel over it and extend it out to the sides a bit????
I don't remember going thru this the last time ((15 or 20 years ago) I raised baby chicks. Of course then I was still working and hadn't the time to fuss like I do now.
