You've neglected your horses' hooves since December, and now you have to pay the price - literally. Get a farrier out to trim them properly, even if you can't afford shoes, you can surely still swing a trim. You don't want to just take a file to the broken section, it will pull on it and cause your horse further pain. The crack isn't caused by a wire or anything else, it's caused by the hoof being overgrown and neglected to the point it is trying to self-correct and break off - but it's broken too high.
I get needing to save money on farrier bills. I'm doing my own horses feet too, however I have done a lot of research and studying, attended a clinic, and still pay a professional to come out every 10 weeks, give me guidance and keep my horses correct while I am still in the learning stages.
Spend the money and get a professional out.
