GoodOlBoy;
I don't know if this site will help you or not:

I've used it in the past to get homing pigeons for dog training....took me a LONG time to find those homers! One thing I do like about the site is that it breaks it down by state, so you can check for things in your state (or a nearby state) without having to go through a whole bunch of ads.
One thing I will say....check the site daily (or at least fairly frequently), as some ads seem to come and go pretty quickly....there was an ad on there last week for some quail (I'm looking for some for dog training) and after a few days, it was gone!
Your post brought back some memories from my childhood....my Uncle raised hogs, and we didn't throw away much of
anything...if we couldn't use it, it was fed to the hogs: spoiled milk, leftover scraps from breakfast, carrot & potato peelings....all went into the 'scrap bucket" and it went out to the hog pen in the evenings. Only thing they didn't get were meat scraps (those went to the dogs). My Uncle even got the out dated milk & ice cream from the local 'party' store a few miles down the road....I can still hear those hogs slurping up melted ice cream in my memories!
Good luck....hope you find what your looking for.
