My freezer's a relatively dinky little thing. Like a washing machine. But, It holds way more than a weeks worth of breasts of lambs for my three, medium + sized Dogs.
Fresh air doesn't come into it. I buy by the week and feed them chopped off slabs of meat and bone. Simply because that's better for them. My own convenience doesn't come into it either. Just what's best for my Dogs.
Each to their own, I suppose.
Totally agree with that Pete....it ain't about convenience is it....least not around here....fetching, chopping, gutting, skinning, cleaning, bagging, freezing, defros
