Hello- last night my girls were free ranging, normally I only do supervised free range but this time I wasn't outside with them. I looked outside and a fox had one of my chickens in its mouth! I ran outside and scared it away but no chickens have come back. I have found different piles of feathers, do you think each pile represents a chicken? Or is there still hope? I only had six and now I don't have any, is this a lot of chickens for one fox?
