Well I'm sold on those pellets, that's for sure. After a couple weeks I've had 0 problems. They are lasting longer, are about 6 bucks per 40lb bag here and the chickens like them as much, if not more than the pine shavings. I'll be curious to see if these pellets compost as quickly as the pine did. I'm guessing that my ratio of carbon to nitrogen in the compost pile just changed a bit with this switch. The pellets are pretty heavy, I guess that's the only concern I'd have if for example I had a light weight coop with a wire floor or something... dunno, works for me though, perfectly. The pellets I buy are for wood burning pellet stoves, the guy at my feedstore said they were the same as the ones for horse stalls. We get just cold enough here where a lot of people have the pellet stoves so there's always a supply. I'll definitely be putting sand in their run though...some at least
