I'm getting ready to process my COB 500 Cornish Cross. We've got 29 that will be ready in about 2 weeks and I'm wanting to find a way to compost all the leftover parts like head/neck, feet and feathers. We generally are recycling minded and I don't want to throw away valuable nutrients that could benefit my garden but I also don't want a lot of recognizable bones and feathers to build up in the soil. Any suggestions on the best way to break them down? I've considered a wood chipper but so far, all I can come up with is getting a meat grinder and sending bony parts and feathers through it. Do you all have recommendations on a meat grinder that is up to the job? so far, it looks like the STX INTERNATIONAL STX-1800-MG is an economical option, does anyone have experience with it?
