Chicken feet is a staple at ethnic grocery stores. They usually have pig feet too. Getting a human supplement might be cheaper per dose for joint supplements. You can also buy bulk green lipped mussel. I get Jarrow True CMO from swansonvitamins(dot)com and also use Actiflex 4000. I get the horse version because I don’t like the beef flavor in the dog version and give a very small amount. This is from folks in my local raw feeding group:
