Tracy, a big HUGE welcome from KY! Sounds like you have it all planned out, so good luck with keeping FOUR hens. As you can see by reading on here, it is so fun to collect birds. I have a dream of having a Green House/Coop for my brooder, keeping the chicks underneath the shelves. Enjoy this wonderful site and get your son involved, chickens can be very therapeutic for autism I understand. HenZ (L&D RN)
