I have a mixed bag (large and bantam) of 12 pullets in my basement that are now approximately 6.5-7 weeks old... all are fully feathered ( one is late with some feathers coming in on back) but no downy fluff left on anyone! Amazing how fast these buggers grow! Anyway I am in NE Ohio where despite some weather in 70s/80s in this freakish spring, it still has been cold at night! When would be a good time to put this crew out to coop? I am not cleaning there brooding box out every few days because of smell issues! Not to mention how much dust they are putting off in the room they are in! I don't have anyway to utilize heat in the coop they are going into.. Also they will be locked in their own coop for awhile before being introduced to rest of the flock (much older hens and roos)! I plan on putting a thick layer of pine shavings down in the coop when they go out but just not sure when to do this.. I would prefer if possible soon because with the size they are and the mess they now create it is becoming a chore!!! Advice???
