Making dogfood and it fluffs up???
I am pressure cooking chicken, putting everything (bones and all) in a commercial size grinder which makes everything super ground down. I then add cooked rice, a vege mix with spinach, eggs (with shell), broccoli, cauliflower, squash, carrots (all has been cooked and then blended together) and pinto beans. After all is mixed, and refrigerated or frozen, the mixture starts "growing" and getting really fluffy. WHAT is going on? WHY does it fluff up? It also doesn’t smell very good. I have tried to refrigerate everything quickly but is hard because of the volume involved (I pressure cook 60 lbs to 70 lbs of chicken). I have added the same stuff (rice and veges and eggs) to ground beef and turkey and it doesn’t fluff up. I just want to make sure it is safe to feed the dogs. Thanks for any help
