My 10wk old alpine bucks are both having issues with their horns. I got them when they were 8wks, both had slightly flaky horns when I picked them up but I figured it was normal/a sign of having been sick (both had sore mouth at 4 weeks old, were clear for over a week before I picked them up). Now one of them is having a lot of peeling/flaking on the top half of his horn and I'm concerned because it seems to be spreading down his horn, and one of his horns even looks like it's starting to whittle away.
The other one (an ober/alpine cross, also 10 wks) horns are not really peeling or flaking any more, but they're growing in with very noticeable rings about every inch or so. The rings look like cracks but they don't seem very deep.
HOWEVER, this morning when I went out to give bottles, he had a deep crack down close to his skull, about 1/2 inch long and maybe 1/16 inch deep, and it had filled with a blood clot (didn't appear to have bled when it cracked, no drips anywhere). He has a similar crack on the back of the other horn. I put iodine on it and bandaged it this morning. When I took the bandage off a few minutes ago it looks much better.
My questions are:
Why is this happening?
Should I be concerned?
Is there something I can do to help strengthen their horns?
Should I put some sort of sealant on their horns to prevent the breaks from getting worse?
I was planning to band both boys at 14 weeks, but now I'm concerned about their horns and thinking maybe I should wait longer. They have free access to alfalfa, grain, mineral, baking soda, and water all the time. I treated for coccidia with toltrazuril about 4 days ago. Fecal came back clear at 9 weeks. Any ideas about whats happening here? Pics below.

Alpine buck's horns from the back. You can see how the cracking and flaking has gone all the way around one of his horns. It looks whittled down.
Ober/Alpine buck's horns. You can see the rings. The area circled in red is where the deeper crack w/blood is.
Close up of the crack. He was moving around a lot so it was hard to get a clear picture, sorry.
Close up of the crack after a few hours. You can also see how dramatic the rings in his horn are.
Any help is appreciated!
