So I know a lot of people are against putting heat in the coop but my 7 week old chicks are used to being inside my house at 70 degrees and I want to wean them off the heat. My husbands allergies are bad so I want to get them outside ASAP. The outside temp at night is about 30 degrees. I had a handyman hang these lights inside and he boarded up the nesting boxes and the entrance to the run (temporarily) so at night there are no drafts other than the holes for ventilation. I plan on using the heat just at night for a few weeks until they are acclimated. What temperature should I be aiming for inside the coop at night? Also could it get too warm- I tried it out at 5pm without the chicks and it was 48 degrees out but 77 in the coop. Should I lower the wattage ?? I have 250 watt bulbs.
