Foxy still won't get on the roost but she is much more mobile than she was. I saw her stretch and flap her wings. Some of the other girls were dust bathing and she just laid down and let them throw stuff on her. Lazy chicken. She is actively seeking food on the ground, scratching around, and going after treats...not at full chicken speed but acting like she is on the road back to normal.
I haven't let them out to free range since the fox attacked because I don't have time to just sit there and watch them but with the doubled run size they don't seem to mind much. I scatter some food in the straw in the run and it keeps them busy looking for it. I also built a dust box for them and they spend a good bit of time there.
