Ugh, it's gotten hot here all of a sudden, and the house is heating up. Chicks are now 4 weeks old and I have started turning their heat lamp off during the day when the house is at 70, they are totally fine with that. But today went up to 90 outside and the house went up to 79.... Do I need to turn on the A/C for them? I know my grown chickens can handle up to 90 ok, over that I need to turn on the mister and ice their water etc... but chicks? I imagine they would probably be best under 80 at least. Who has experience with brooding in hot weather?
