Cracked Hooves - Drought?

[Charlie Horse]

I've never had trouble with a goat that has a crack in the hoof. They have a spare toe anyhow. I have a goat that grows his hooves out 3x as fast as any of the others so I sometimes get behind on his trims. I just trim as usual, and any cracks are just ignored. He never limps or acts sore so I doubt it matters unless you're planning some kind of epic long hike on lava rock or something.
