Reproductive cancer is not contagious.
Neither is getting fatally mauled by a GSD.
Or an incurable vent prolapse.
Or a hen and a cockerel that flew into the coop/run wall and broke their necks.
Or a hawk strike fatality.
Regardless, most diseases of poultry would not be communicable to mammalian predators.
Last I checked, I don't have disease in my flock.
I will ask if an animal in the wild dies and other animals feed on it are we going to say was that animal okay for them to eat?
I don't think so.
