Lamancha with ear wax stones.

One of my boys has elf ears and he has had issues with wax build up in one ear since we got him as a bottle baby. I've been gently massaging the wax up the ear canal and gently swabbing it out as needed (don't worry I'm not sticking anything in his ear canal).

In the summer, the wax seemed to bother him quite a bit. He would shake his head and scratch at his ear. The heat kept the wax soft, so it was easy to remove with a stone here or there. Now that it is cold, the wax seems to be staying more solid. Yesterday, I removed a solid stone that was about the size of a small almond. He didn't seem bothered by me removing it.

Is this common with lamanchas and is there something I should be doing other than cleaning out his ear on occasion?
