I use wood chips from TSC and have found that there is a terrible dust problem in my coup. It collects on everything and I am wondering if I should be using something else to use as deep litter. I heard of wood pellets but don't know if that would be the fix. It seems like it could cause respiratory problems if the chickens continue to breathe it in. Also it collects in the water and food. Any suggestions? (I have 4 hens) Also I have a collection tray under their perch that gets cleaned out daily with cat litter in it.
