First you have a great piece of property. How far from the house to your barn? The barn looks very well laid out. Are you just keeping poultry in the barn? Your barn you said was insulated that is good, you'll be fine be fine. A couple things I'd like to run by you, first I'd put some clear panels on the roof for light, second how many birds are you going to keep in the barn? You will find your birds will do better when they can go outside (weather permitting) them being able to get bugs and stuff is to their advantage yours to really. Please upload pic's when your all settled in. One more thing you'll save feed if you keep feeders off the floor some. Not in the brooding area just the laying area. Thanks for sharing you'll do great. Chicken eggs their are expensive right? Last I knew like $6.00 a doz. Is the building setting on a slab?
