Thanks, everybody, for the suggestions. I've saved the pdf about goat disposal, and taken to heart the many comments you've made. I also found another thread, "What to do with the Rest" which I hadn't seen before posting. I feel confident now, and thank you all for your generosity!

I would just give fish guts straight to chickens personally.
Yes! I would, but I've heard that feeding fish to chickens makes their eggs taste off.
Hoping David Goodman or someone else who knows can comment. How do you capture the nutrients from the non-edible parts when you slaughter animals for meat? We've processed two tuna recently. I buried the carcass from the first in my not-very-active compost pile. Copped out and put the carcass from the second in the trash What to do?
I'm also looking at how to compost remains when we cull a few chickens in the near future.
