I am getting 3 6-week-old chicks this weekend, so I am hoping that they can go right in the coop with a heat lamp at night. Having my previous 4 chicks in the dining room was charming but I am -too- ready to have a dust-free house again!! One question, how hot is too hot at night? My 250 watt bulb is keeping the coop about 90 degrees early in the evening when I put them up, getting down to 72-73 by the early morning as the night cools off. I feel as if I am baking the poor dears in the early evening. They all seem happy as larks, but I worry. It's what I do. I even have a t-shirt. So, should I lower the wattage of the bulb? Should I plug one or more vent holes later in the evening? Throw a tarp over it to add a dead air space? Here is a photograph of our new coop/tractor. Thanks again for helping me! -cackalacky *Reposted from coop forum.
