I used to do something similar. Put the squirrels in the crock pot with a can of beer for liquid. Keep the cover on, turn it on medium for about four hours, and then turn it to low till the meat is falling off the bones. Take the meat out and it is easy to shred. Then back into the crock pot with barbeque sauce (no beer or other liquid) for the last hour or so. It comes out tasting like barbequed beef.
As a bachelor I would pressure cook them for about thirty minutes and the bone the meat and add it to canned stew.Now I use an Instapot. First I braze the quarters in a little lard. After that they go into the Instapot for thirty minutes. Then they get boned and turned into squirrel chili or squirrel tacos.
