Okay, as long as they have a way to get away from the heat, everything should be good. While they're a bit expensive, I highly recommend brooder plates. I just ordered 2 11"x11" Sweeter Heaters (on sale at MPC) for my upcoming broods. I have an 11"x16" that works fantastically, but needed a couple of smaller units to handle the small weekly batches I'll be hatching.They are a couple of days past 2 weeks old now. I built a larger brooder. It's 2ft. X 6 ft and 18" deep. I just went and checked and when sleeping there is a big dog pile of birds and a couple scattered just outside the pile. They have a ton of room to move away from the heat, and they are moved away from a direct line of it. I'm using the 125 watt infared white light bulb. I think for future flocks, I'm going with a ceramic bulb.
