This is my first post so I hope I do it correctly! we need to move our hens about 100 yards from where they currently are. although we have a somewhat portable coop, we can't really put all of the hens in and move it. the distance is too great and i fear it wouldn't be safe for the girls. i've heard that you can successfully move chickens at night. is this true and if so, how does it help? any suggestions would be very welcome.
