The other day I found two hard crusty knots in my horse's mane: kinda grainy scab(s) that made a ball about the size of a large pea or small grape. Underneath was a circular surface sore. I've seen these before in manes/forelocks, but not in a while and I still don't know what they are or what I should do with them. Any ideas? Are they a problem? Sorry I didn't think to take a picture. Thanks!

Sounds like tick bites to me, too. Since the bugs are coming back out just make sure you check. It's quite frightening how many things you'll find on your horse after a hack in the woods. I once went on a little walk in the woods for about 10 minutes. I had 2 ticks on my and my mare had 6 on her. Needless to say, I don't go into the woods anymore!
