You were right, it was going to be the floor, based on what the guy who did the dozer work said about how he used it for his chicken barns, however, after research, I decided it might not be what I wanted. It's fine for the base of the building, tons cheaper than concrete, much smoother than crusher run/gravel, but after thinking about possible dampness factor coming from the ground, the number of elderly birds I have with severe arthritis and how that might affect them, and researching online about dampness in metal buildings, we decided it might not be the best choice. If we changed our minds, no big deal to cut it out around the perimeter. Needless to say, nothing is set in concrete yet, pun not intended. We could put stall mats on top of the vapor barrier but it would take quite a few to cover the entire 480 sf. and if we only did it in the pens, how much moisture would wick up through the rest of the building? Still thinking but we had to put down the vapor barrier so they could sit the frame on it.
Some articles I read during the research:
From what I've read, there are a few basic things that cause moisture problems in pole/metal buildings.
1. Inadequate ventilation.
2. Lack of vapor barrier under floor.
3. Lack of insulation, or proper type and method of insulation.
3. Building is placed on a site with inadequate drainage or high water table.
We have plenty of control of ventilation, the roof and walls will be insulated and the site will drain fine. The only thing in question is the floor.
