We have a large shed like building. Is it ok to put 2 wk old chicks in there with heat lights on? The building is (naturally) outside. I live in Missouri. Weather in the 70s - 80s. I am new, and have 44 new chicks (Americaunas, Red Sex Link, Black Sex Link, Rhodle Island Reds, Buff Orphingtons, 5 Polish Crested). Appreciate your feedback.
