My chicks are about 5 weeks old almost fully feathered, like 90% feathered I would say. It drops down to the low 40's at night and our coop is kind of insulated but has some windows. Will my chicks be okay at night in the coop if I use a heat lamp? During the day we have been turing it off and putting them in the sun/shade in their enclosure and they are doing fine, I am just worried about at night..
Any suggestions would be great thanks!
