They also take up valuable floor space.
...and I have to ask, why is your ceiling completely covered (with insulation?)?
It's blocking the soffit venting.
For us, valuable floor space = more places to hide eggs that I can’t reach!
There are vents on the back side of the barn, behind the roosts, that are closed off in the coldest winter months only. There are 4 windows, the south facing ones are almost always open. There are exterior vents between each roofing joist to release any potential moisture. There are vents on both sides of the barn at the highest points. The barn door can be left open at all times because the run is fully enclosed with hardware cloth. The entire barn and run have hardwire cloth and wire extending out 2 feet along the bottom. In addition, the chickens and geese share a back yard, 1.5 acres, that is fenced with 7 foot high fencing made with deer fencing, plus 3 feet of hardware cloth on the bottom portion. It’s not perfect, but it’s what we have. So far we have never had a predator in our fence, but we cannot stop the hawks. We do have one of those crazy arm things running from early morning until the chickens go to bed.
The insulation was put on the ceiling because for one thing, it is extremely cold, and also, when there are extreme dips in temperatures, I like to give them radiant heat, which seemed to almost completely escape up and out. The ceiling insulation has allowed the radiant heat to warm the barn about 20-22 degrees. Prior to the insulation, it raised it 12-15 degrees. I want strong birds, but I also don’t want them frozen!
The other reason for the insulation is because the metal roof was so loud when there was a storm, my birds looked like they might have a heart attack. I nearly had a heart attack when I was in there. I hate metal roofs.
The barn interior is 10 x 20 with very high ceilings for 27 birds, and has never had any odor. The poop boards are scooped daily. There has never been any condensation on any of the windows. Hopefully ventilation is not an issue.
Thank you for looking out for any flaw designs I may have though. It is very much so appreciated. I’m always trying to make their space better, and I will fix anything that could possibly be a problem for my birds!
