Thank you for the reply. I think i'll pass on the meat composter. Sounds like too much of a mess to deal with. Not sure id want to throw fish guts to the birds though, iggghhhh.
Well, my in-ground composters worked very well, but when I got my chickens I just started throwing all our kitchen scraps, meat, etc... to the birds. So I dug out the in-ground composters as I no longer was using them. But let me add that it was not too much of a mess to deal with. I composted all our kitchen scraps, not just meat, in those in-ground garbage can composters. Covering up rotting meat with a layer of wood chips, or leaves, or grass clippings really knocks down the smell and the tight fitting garbage can lid sealed the deal to prevent any offensive smells.
There is nothing wrong, IMHO, in feeding fish guts to the chickens. Our feed store here carries a commercial high protein fish based commercial feed. I would think that fish based high protein commercial feed is probably fish guts dried out, ground up, and pressed into pellets. I just give my chickens some fresh product every once in a while.
Fresh fish guts don't smell bad. But in the evening, I bury any remaining fish guts down into the chicken run litter. If the chickens don't want to eat it it all, then it's time for the worms to feast on the remains. In the end, it all gets broken down and mixed up into the chicken run compost. Fish fertilizer is fantastic for the garden.
