Raptor foot stresses very different from those of poultry. I very seldom see bumblefoot in game broodfowl that can reach a decade or more in age. Perches we use are round and sized so toenails of opposing toes barely overlap thus mechanical stress on foot likely low with roosting.
And game fowl are relatively lightweight, so their risk of bumblefoot is minimal, regardless of other factors.
