A few days ago I noticed a crack in my horse's front, right hoof. No one was around to ask about it, but it didn't seem to bother her at all. I went today and noticed a crack in her other front hoof. The cracks are pretty much identical in regards to location and size.
I lunged her for about ten minutes and she shows no signs of either hoof bothering her. As you'll see in the pictures, the cracks aren't large, and they are both across the hoof instead of up and down.
I know it is kind of hard to tell in the pictures, but it is definitely a crack.
I'm just wondering if this is something I should call the farrier for and if it is even anything worth worrying about too much [since like I said, she shows zero signs of it bothering her at all].
Yes, it is quite unclear in those close ups. I'm presuming the clearest horizontal lines at the quarters are what you're talking about? I'd say they're probably from abscesses which burst a fair few months back at the coronet. Or perhaps from a lami attack then, which caused a fault, which has opened up recently because of the pressure it's under at the quarters. Not necessarily anything to worry about, but I'd just make sure the feet were kept well balanced with as little extra stress on the walls.
The obvious rings/ridges indicate that the when the bottom half(at least it appears top/recent is better) was at the coronet band the horse may have been suffering frequent lami attacks.
