I feel your pain.. my chicks are 1, 2 and 3 weeks old. My initial plan was to transition a 6x8’ aluminum greenhouse with polycarbonate panels in roof and sides. Now I’m beginning to wonder if it won’t be too hot for them in zone 7b, charlotte, North Carolina. If I cover the panels with the shade cloth y’all are talking about, will that block the heat or would it be best to just use the frame and remove the polycarbonate panels and use plywood for roof and walls? I just thought it would be good for warmth winter but summer, I don’t won’t them to get to hot!! Help!!!!
