Since we're residential my thought was the $12 eliminates the mess and clean-up here, as well as the emotions tied to the deed itself since I'm a wimp and husband is no better. It's the back-up plan for extra boys.. we'd rather eat them than give them away for someone else to do the same. If I can't sell them for what I have in them for feed costs and care... then we'll take them all and pay the $12 unless I find a better deal elsewhere that doesn't skimp on the quality and clean facility. The $12 guy is USDA inspected and all that.
Doing the math... with the gourmet stores wanting $30 + for duckling, we'd do a little better than breaking even eating our extras.
Plus I've hand plucked scrawny roosters before and that was a chore... can't imagine a bigger duck. So until we're on a farm, I'm ok with the $12.
