I was wondering because when I went to TSC today to get pine shavings to clean the coop out, they were out but I did see the pine pellets. I thought about getting some, but in the end decided not to. I was to nervous that the chickens would eat them! I didn't know exactly how big that they ended up after they expanded, so I thought it was best to hold off until I found out if anyone has ever used them or not before in their coops. They look like you would end up with more per square foot, so they would be less expensive in the long run, BUT like I said before, I was scared the chickens would eat them! Anyone???
