I have been using corn cob litter inside my coop, and it seems to be working fine. The package says it's for small animals and birds, and that it's "highly absorbent and virtually dust-free." I just started sprinkling it with food grade DE to do the deep litter method. I haven't seen corn cob litter suggested for coops on this forum or any of my chicken books. Anyone know of any reason I shouldn't use it? thanks!
