Six weeks or not, I think you need a new farrier. It's not just the length but the angle and slippering that's very bad, and can't be helping matters in the slightest.
Now, for the radiographs, I am NOT a vet or farrier, but I'm going to give it a go, and you tell me if I'm right.
I see sidebone developing. Is that from soft tissue injury? Also, her legs are crooked--conformational shortcomings? Joints don't "line up." What is with the ballooning-out areas of the pastern bone on the lateral (left) side of the second view? In the first view, is that the same thing on the front (right)? It looks like an arthritic lip. Ringbone? Her coffin seems to have an excessive angle to it, but I'd be willing to blame some of that on your farrier, as her heels are way too high. Has she foundered in the past?
Edit: Just saw Cherie's post. Maybe a great minds thing, maybe not....
