I had them outside for over 2 hours yesterday and they loved it. The average overnight temp is high 30's to low 40's. Daytime temps 60-70.I built an indoor coop in my shed any ideas of how soon I can leave them out there? They are white crested polish if breed makes any difference. I will leave heat light on outside but I dont know if that will be enough or not. Helpful ideas would be great.
