Well, you learn a new thing every day and I figured I'd pass on what I have learned in the last 12 hours! turns out a trending diet for pets is the Biologically Appropriate Raw Food (BARF) diet and it involves ground bones. turns out quite a few reviews are out there rating grinders in terms of their ability to grind smallish bones, like those in chicken necks! after reading a bunch of reviews I narrowed it down to the STX brand, which is a consumer level/light commercial grinder brand that seems to be holding up to the tests, and most importantly costs less than $200. I narrowed it down to two versions, the STX megaforce 3000 and the STX mangnum 1800W series, the 3000 being the more powerful. I found one review that said the 1800 was the way to go for grinding bones. I found this perplexing so I called one of the main warranty repair companies, mercantile station 2, and asked them which in their experience with repairs, holds up best for grinding bones. The guy on the phone, "wow, I'm glad you called, the 1800 is the only one with the appropriate screen/blades for grinding bones, even though it has a lower locked wattage than the 3000". so I may end up making dog food out of my leftover necks/heads, organ meat and feet, then seal it up in meal sized servings in the food saver, freeze it long enough to eliminate food born illness and presto, offer up gourmet treats to the dog. people rave about the noticeable benefits in health to their pets, so I might as well give it a try. If we end up with too much, then any extra can then get composted. and or course, the main benefit of having a meat grinder is being able to make things like chicken sausage and burgers. this leaves the feathers and entrails. I may give the feathers a run through the grinder or just throw them in the trash or yard waste, they are really a small % of the overall mass and likely have little to no nutrient value to the garden. the entrails can get layered in to the compost and surprisingly, as long as they stay covered they decompose readily without stinking up the place.
