We're having pretty cold weather now -- for central Texas. Temps for the next 4 nights will be below freezing, but will be in the 40's to low 50's during the day. And yes, of course, I am building a chicken coop in the winter. I'm using white barn paint inside the coop because it's self-priming and saves me a step - but the directions say to paint when the temps are above 50 degrees. Is it safe to use a small bathroom-size space heater, set on low, inside the coop during the night? We use a similar heater inside our well house that cuts on when the temps drop below freezing - but I'd need it warmer for the paint inside the coop. If I don't use the heater, what would happen to the paint tonight when it freezes? Dry time is 8 hours (should only take a couple of hours to paint) and it shouldn't hit freezing until 1am. Also, how long do I need to air out the coop before letting the hens stay inside the coop overnight? I have plenty of ventilation in the ceiling and the end caps of the roof, but I'm sure it will still have paint fumes for a while. The chickens are in a tarp-covered hoop coop for now - but I'd like to get them inside (they would probably appreciate it too!) Thanks for any help with this!
