I would love a opinion on this. I've just took on 3 9 day old chicks. I have a home made brooder with a red 100w heat bulb in there. The chicks so far are laid under there sleeping. I woke them up, they ate a bit of food then went back to the heat spot to sleep. It's now at 30°c in there. Is this warm enough or two warm? I'm new to this... had them 3 hour!!
