So I will try to be short and to the point. I have 6 babies (4 days old) in a black rubberized horse trough brooder. It is about 18 inches tall, 3 feet long, set up in the garage. Yesterday the weather was a high of about 75. Today 54 is the high, in the 40's tonight. The garage is unheated. Will the babies be ok as long as the heat lamp is warming their area? Or should I also heat the garage? I can put a small heater near them, I just hate to do it since they are dangerous. Or I could partialy cover the brooder with plywood, right now I am just using a screen. Oh one more thing we live in Texas, and well cold is a novelty. Hope to hear back from someone who is use to the cold.
