If they get good food like seeds and wild stuff, they should be OK to eat. It’s just the garbage-eating city pigeons I’d stay clear of. Bag a few of those farm pigeons and give them a try. Plenty of dove recipes online, or just fry ‘em up.
They do sound good- better than tree rats (squirrels) which I really don’t care for- but I’ve only ever had em fried and pressure cooked (which made them more tender at least), but n3ver had it in stew which I bet would be really good.
