We got 4 heavies, 2 guineas and 2 ducks that are about 5-6 weeks old, the chicks are getting their feathers pretty good. They have quickly out grown their brooder. I was wondering if it is okay to move out to their coop with a heat source...if so what is the best heat source. We live in Missouri and the temps are getting up into the upper 50's and up during the daytime hours, but the nights still been dropping low into the 30's. Some guidance be very much appreciated. Thanks.
