Our run really smells bad! It is new this spring. We have 24 teenagers in this run. It is very large, about 20' x 40'. We had a couple of pieces of metal roofing leaning up against the side to give a little shade. We put the feeder and waterer under this shelter. This is the We have had some heavy rain recently and it started to get moldy where the feed had spilled, so we moved the shelter to let the sun dry it up. It really smells! I believe it probably is where the feed has been spilled and billed out. Just a reall sour smell. I was wondering if anyone uses anything in their run for odor? I was thinking of maybe sprinkling lime powder, but think it might be to caustic. Any suggestions or opinions? Thanks!
