I live in Kansas and our daytime temps are averaging between 65-70's but, our night time temps are still dropping into the 30's. Is it safe to move my 5 week old chicks out to the coop if I give them supplemental heat at night? Some of my chicks are fully feathered (those one I want to move to the coop) and the ones that aren't will continue to stay in the brooder for another week or so until they have all their feathers. Also, will I have problems adding the chicks that aren't ready to be in the coop if they are separated for roughly a week or so? Suggestions and help anyone?????
