I think I'll be removing the round pen.
I put back up the easement fence by the barn & been using that odd shaped yard instead. It is about an 80ft round? So better for joints. =/
And, I've been getting nowhere with her hooves.... Took pictures yesterday and realized that I wasn't being aggressive enough. So, this morning, I went back and removed heel and toe much further & there's finally a bit of progress going again! *phew*
On rubber in today's pics, so it's a mess to see the flat heel bottom.
I don't know much about horses but I recently watched a video where someone had a rescue horse with TERRIBLE hooves. Looks like you have a way to go, bit by bit.
