New to the site & chickens, too. This spring, we bought 30 chicks, they are two weeks old now, and we've been working on getting the coop ready. Our first one is 8x8, and it's purpose is to house the 20 meat chickens we're doing... We'll build a 4x8 for 8 - 10 hens next. We're from the Texas panhandle, so it's warming up nicely. We finished (or so I thought) our coop yesterday, and put the chicks in last night. Have two heat lamps running so they would be warm enough over night (low temp around 60). Everyone survived the night, I thought we had it whipped. It got pretty warm this afternoon, up to about 95. Checked on them and they were panting heavily. All of them. We brought them back inside, everybody's good. I crawled inside the coop, and while it was warm, I didn't think it was THAT bad. Put a thermometer in there, was probably about 93. At that time, I had two windows, one on the south side, another on the north that are 1'x2'. our prevailing winds are south-west, and I've got a privacy fence on the north and east sides (about 2 foot away from the coop). I did some reading and figured out that wasn't enough venting, so I added one that was 1'6"x2' on the west side, and another that was 1'x2' on the east, so now I've got vents on all sides. Temp went down to 87 or so. Do you think I've got enough ventilation, what else can I do to make sure the chicks are comfortable?
