I have 5 barred rock chicks who are just over 6 weeks. They’ve been in the brooder in our garage without supplemental heat. We do however have a space heater in the garage to keep it over 65°F since temps are fairly cold at this point. We’re finishing up the coop now but are hoping we can move them in under a week. They all seem fully feathered but temps are averaging 20-30°F at night with a few warmer nights. Going into December in the Midwest, we’re having warmer days the next week but temps could drastically change overnight here. Should I turn off the space heater to officially acclimate them prior to moving them? I know they’re hardy chickens and they don’t seem to miss their brooder heater but I’m just hesitant to drop the heat entirely if it’s too soon lol.
