So I have 6 4 month old silkies. And I freerange my flock a lot. But i never freeranged my Silkie chicks i have lost 2 chicks to a hawk. I have 2 fears one is hawks, the second one is that other chickens might hurt my silkies. they're separated but they do see each other when i put my silkies in a small tractor so they can eat some grass. Anybody free range there Silkies? any Tips?
