Ok, I have put my Roosters inside the barn for the winter in smaller cages while all of the girls are together in a big coop. Everything is good but I know we need to supplement the Roosters because they won't be getting outside in the sun for the winter months. I read on here somewhere that theres a light you can buy that will give the vitmain D they need. I can't remember the name of the bulb. Someone said they had bought one at Walmart. Thanks in advance from Georgia!!!
