if they are free ranging im sure they are getting enough grit, even a dozen stones at a time helps.... i feed my "captive" chickens hay from a feeder, and their FF is 40-50% alfalfa, when i butcher these birds, even after holding back food for 24hrs, their gizzards are full of stones and greens, i mean chock the frig full, no room for anything, and these are healthy birds, so im not saying i doubt your cause of death, but im just saying that i believe the gizzard naturally is on the fuller side, but my young birds also have the gizzard of much more mature chicken, idk if thats normal or not.. but if your birds have smaller gizzards it may be because they are filling up on "cheap" feed, meaning they dont need stones to digest it, its already chewed up for them so their gizzard doesnt have to work half as hard...
Our free range birds are let out in the am, they stuff themselves full of grass then later in the day they are fed fresh corn that we grew for them, we've never had any problems...
what are your symptoms before death?
