My chickens were free ranging when I was gone. When I got home I found a lot of feathers right up next to my house. I looked at them and they were from my roo. The only other roo I have doesn't come that close to the house, so it wasn't a roo fight. The girls wouldn't have done that. I went down and checked at the coop and everyone was there and no injuries I could see. Seems like something just pulled out a lot of feathers. What do you think it could have been? Should I put them in lock down and quit free ranging for a couple of weeks.
