Hey Moes,
We are in Nor Cal. Just spent the month of June traveling through your beautiful state.
We have been feeding raw to our pups for almost 20 years, not saying I know it all because I certainly don't, but have managed to pickup an idea or two along the way.
You said you found a supplier but they sell in bulk, what's wrong with defrosting, resizing, and refreezing? My brother has Poms and he makes their meals up from self ground material and freezes them in meal sized balls on a cookie sheet then bags them for individual use.
Check with a local butcher shop/store and see if they won't grind up chicken leg quarters, bone and all, for you. We use them all the time.
On that month long tour of your state we made all the dog meals up ahead of time and froze them, a bit problematic as we have a German Shepherd and a Border Collie, think portable freezer.
Like I said earlier, lot's of effort
but the animals health and vitality
are well worth all the work.
