Built my brooder in my coop. Thought this was a perfect idea to keep from brooding in my house. All is well with the chicks except the light from the heat lamp is keeping my grown flock awake. I went out at 4 am just to check temp on the chicks and some of my hens were already getting down from the roost. I have a dark colored blanket draped on the front of the brooder to keep drafts out but the top of the brooder is hardware cloth with the light above it. The light shines on the ceiling and casts just enough light toward the roosts to keep the rest of the flock awake. Should I move them to a cage of some sort in my garage at night or maybe try to hang a tarp between the brooder and roosts ? Any suggestions are welcome. Thanks
