My chin won't eat pellets no matter what. I have tried three different brands, but he still won't eat the pellets. If the brand has different items in it, he will eat all of those, but leave the pellets. He has an unlimited supply of hay, and I make sure to give him a treat everyday. He obviously isn't starving, but is he getting enough? I haven't tried getting alfalfa pellets. Any thoughts on why he might hate pellets?
