Thanks for your responses! This is very encouraging.
DobManiac: I've already put him on chicken for about 1.5 weeks. I gave him liver this morning and he gulped it down - he's a dachshund so I don't that's a problem for them since they're bred to be greedy

. I think you have a good suggestion about bone + organs for one meal and muscle meat for the other. I will switch that around and try that out. I feed so many different parts of chicken because I get a whole chicken from the butcher and he cuts it up very nicely for me.
phoebespeople: I haven't fed him beef back ribs yet, I was tentatively planning the menu and I would go out and buy all the stuff this weekend. What kind of beef cut would you suggest as the RMB? I'm trying to see if there's green tripe anywhere in my neighborhood so I don't have to buy it in bulk online!
I'm not sure if I want to add pork to his diet until maybe a few months in - turkey, duck, rabbit and lamb for sure. I have a great butcher shop that sells of these things, although it's a little more expensive, he cuts everything up and it's all small-farm owned, which is why I'm actually ultra excited to be feeding him raw.
Thank you guys so much for your suggestions!
