i have a few frozen birds that i am planning to mount./ which some are pretty good, but some are just covered with blood. how can i get the blood out? after skinning them out an washing them. also what is a good way to get the fat out of a bird skin. i dont have a flesher and the wire brushes ive tried to use just dont work. i have no money right now also. is there a way i can get the fat off the bird skin without ripping it, and also what about the blood?
