My trimmer thinks this is what Lilly has, and I tend to agree. Since she emailed me back with her diagnosis, I did a bunch of research and looked at hundreds of pictures, and this seems to be what's going on with her hoof. Seedy toe can occur in non-laminitic feet with long toe/low heel conformation, where the hoof wall separation and subsequent infection are the primary features. It may also occur in feet with poor front to back balance and may be predisposed by poor quality hoof horn.
All the articles I read make it sound like I'm doing a shitty job as a trimmer for my horse. I work really hard to keep her hooves balanced and to keep her toes short, but clearly I'm doing something wrong. And now I have a pretty big issue to fix. My trimmer said she's seeing this a lot because we've had such wet weather that past couple months, and something as simple as a little toe crack can allow bacteria in where they work their awful magic.
So probably what happened is, the bacteria got inside her hoof wall and chewed away until her hoof wall was compromised, and perhaps when she was out goofing off, she managed to break off that piece of hoof, exposing the now giant crater.
She recommended I use a dremel to cut away all the diseased areas until I hit solid wall, and then treat with oxine. There's no way I feel comfortable using a dremel on her hooves, so she said my hoof knife would probably be just as effective, so I went out today to cut away the hollowed out area. I could only find oxine online and it'll take a while to get here, so I bought a soaker boot and a gallon of apple cider vinegar.

Here's her hoof after I was done trying to chop away the diseased areas:

I'm working with my trimmer long distance, but I feel a little in over my head. And I feel like I let Lilly down. I just hope this is as bad as it gets and I can get her back on track. It's going to take a while for this to grow out, and I'll have to pay really close attention in the future to keep this from happening again.
