I have over 100 chicks, 14 weeks down to just over 1 weekers, 2 coops, 3 brooders in my basement. I am so done with all the dust. I switched to crumbles and that helped a little. I asked dh to build a coop to put next to the house so I can put a light in it cuz I have almost 4 dozen eggs in the bator (LAST hatch this year)and want to get all the brooders empty before my current hatch pops in 2.5 weeks. He is going to make it 4Hx4Dx8L. Do I need to insulate it if there is a 200watt heat lamp in there? I don't want to slow bake my chicks but want to make sure it will do ok all winter. Thoughts?
