Hi everyone. My babies are coming home either tomorrow or Thursday. Our makeshift brooder is all set up in front of a big window in our basement and we have a heat lamp over hanging over the cage. My husband is very nervous about the 250 watt brooder lamp catching something on fire though we have it a safe distance from everything. Anyway, the chicks are feathering in and I just checked the thermometer I placed in the brooder this morning to see how cold it gets over night without the lamp. It was about 52 degrees. Is this too cold for chicks of this age? I read in my book that they will feather in faster if it is kept cooler too. What do all you experts think?
