Is it necessary to have food and water available inside the coop? After the chickens have come in and are roosting for the night I close the opening to keep it warm but the food and water are outside in the run. I have two older chickens and I have never left food or water inside, but now have integrated 2 Black Jersey Giants and two Coco Marans (all four months) into the flock (all are getting along except they won't share a roost yet). Do the younger birds need water during the night? -thanks!
