I tried some Maine's Choice and noticed that the pellet density seems to be less than any other pellets I have tried. If you break a pellet in two, it kind of crumbles with a bunch of small pieces. Not a clean snap like most pellets. There are a lot of small pellet bits in the bag like that. They aren't fines but sort of like big fines. Is it because the pellet mill just doesn't produce enough pressure to get the density?
