Oh dear oh dear. Hoof problems are the worst
I'm glad you have such a good team to help her! Is there any chance one of her buddies could be moved into a stall close to her to keep her company? Idk what kind of things you've looked into to keep her occupied, but things as simple as giving her her hay loose so she can "forage" a bit better could help keep her occupied. There's also those... lemme get a pic real quick
Likit horse toys. Might help keep her occupied? If you search up this subject there's some good ideas - things as simple as a tennis ball hanging by a rope for them to knock around. Maybe a carrot stuck through the middle of it.
Maybe even something like this - make her work for her food. Worth trying; so much boredom and frustration could lead to some nasty (and unhealthy) habits :/
Anyway, I wish her a speedy recovery and hopefully no more problems in the future
Poor girl; she's been let down by people. But I'm glad she has you and your uncle now to take care of her <3
