Hello! This is my first night with my chicks. There are 7 of them. I have a hotter lamp, but won't be able to get it until tomorrow night. I thought this one would be ok. The hot side of the enclosure is 80 degrees...sometimes flirting to the upper 70's. The cooler side is apx 10 degrees cooler. Will they be fine for the night? Thank you for your help!
