I was just thinking about suet cakes. I have like a 3 pound thing of lard back there that NEEDS to be used b 4 it goes rancid and I could put crushed corn and some BOSS and scratch in it I guess. No I don't have a grinder Bee. Hubby always wants to feed the dog my left over egg yellows and I tell him, noooo he's not laying eggs for you and doesn't NEED them. Give them to those poor chickens that are keeping you in EGGS! lol I'm not wild about the yellows but I do try and eat some since they ARE good for you.Maybe even getting those trimmings and grinding them up fine and feeding it raw? Do you have a meat grinder? If not, can you afford some hamburger now and again? Or would just feeding suet cakes be sufficient, I wonder?
