For no reason my flock of white pigeons have been acting really strange. Any young hatch died. The adults go around in circles causing them not to be able to fly. All of a sudden I have had this problem the last coue of days. I think something is causing it becuase it is only killing the young birds- hatch- 5 months old. I started yesterday culling all that looked to have it in hopes of preventing it. I just want to know what eerybody might think it is. I think I have stopped it by culling them though.
