How is she doing today?
Looks like you are giving her good care.
The only real challenge now is avoiding depression. That's our number one killer in our flock. We've had hens loose eyes and half a chest (with the lungs poking out through the visible rib cage - way ickier than it sounds) and they came through fine. Others stub their toe and keel over because they get depressed.
Do you have a companion
chicken that would keep her company? Occasionally we get a
chicken that has sympathy for others instead of trying to eat them like a normal chicken would. They seem to treat injured chickens like they would chicks - get them eating, keep them happy, keep them warm. These are usually chickens that have suffered some injury themselves in the past.
If no companion chicken, keeping her near the flock (so she can hear them) or near you so she can see and hear you, while she recovered will make a huge difference to how well she does.
Please keep us up to date. So glad you were able to save her. Training your own chicken guardian from a puppy sounds like a lot of fun. I think it's wonderful that your dog respects you
enough to obey the drop command - I know so many dogs who don't consider the human the pack leader and that would make things much more difficult. You're doing a great
job!
