So I'll be having chicks here soon and want to brood in the coop under the poop shelf. (I can't have them in my place, and I don't think they'll do well in the shop.) But it's only up in the 40's during the day and sometimes in the 20's at night. I was thinking about doing the mama heat cave and was wondering what y'all think. I'm adding feed bags with hay stapled to the walls. The walls are plywood without installation. I wanna do all I can that won't hurt any of the chicks but also I don't trust heat lamps in the coop.
