Jonathon craigrice awesome, thanks guys!

Jonathon so I’m getting ready to do brats for my first time, I planned on doing venison and pork butt 50/50. My question is, should I grind the venison first and then add my pieces of pork butt to the venison and grind again, or can I grind it all together for the first and second grind? I am also adding cheese, so should I mix the seasoning and cheese at the end and mix by hand? I have no mixer. Thanks!
