I bought a extra large dog cage, had my husband put plywood on the inside and a type of thick foam insulation around the outside, along with plastic wrapped around it. I have 13 chicks some are a little younger than the others so I’m probably only moving about six in there. But my main question is I have 1 red 250 watt light for it to keep warm, and there is ventilation, I live in upstate NY so it’s about 30 degrees outside will they be warm enough. The photo is when they first started but just to give you an idea the wood is on the inside and the purple insulation is on the outside. I’m going out there right now to plug the light in and check the temperature with the thermometer but I’m still worried they’ll be too cold or too hot.
