camping, that's what the guy did who I got my original Seramas. He was up in the mountains, very cold temps, and no heat for them outside of the brooder. He lost a lot, but the ones that survived were cold hardy.
I don't like to lose them. I'm trying to decide what to do with the small coop. Drag to fresh grass? Leave as is and dump rocks in? Needs doors and waterproofing either way. Hoping if I can get part to stay dry then they won't need the lamp. Like a warm dog house. We'll see I guess.
