I am currently using straw in my pekin's run and pine shavings in the coop, I have 0 problems with the pine shavings they're easy to clean up and put down. The straw on the other hand is a pain. I have a feeling it might be the straw I am using because I bought some at TSC and it stayed pretty decent no mold or anything, made it a whole week with no need to clean. switched to a local farms straw it is molding in a few days and does not dry well, not to mention the smell. I have to put a layer around the pool almost everyday. It is crazy. I in the northeast and we are getting a particularly hot summer, every day in the 90s. I mist the ducks with the hose to cool them off, but the smell is absolutely awful. I am using the deep litter method in the run btw. What do you guys recommend for smell/easy clean up
