We are picking up some baby chicks this afternoon. I have a place for them in an aquarium in the shed for now which I THINK will be warm enough but the aquarium is not very big and I think they will outgrow it very quickly. I built a brooder outside and am hoping I can keep them out there.. If I need to bring them in at night I will but I greatly prefer not to. The brooder I built is from wood, solid on the sides and half of the top is also wood while the other half has a wire lid where I will place the heat lamp. It's going to be in the high 30's and 40's the next few nights (60s and 70s during the day) and then after that it is supposed to warm up to high 50's and 60's at night.
