A friend is giving me their coop with two chickens. I would like to place the coop in the back corner of the yard so that any noise from them will not disturb the neighbors. But I’m concerned about getting power out there for a heat lamp. Is there a battery powered heat lamp or heater of some kind that I could use that’s safe for the coop? Thanks for your help! These will be my frist chickens and I want to make sure I am fully prepared.
