It is pretty small, sticking out several millimeters, but it is noticeable upon close inspection and to the touch. I did not notice a tick, and it didn't feel like anything was lodged under the skin.
He is probably okay on the eyecaps because they went clear about two days before the shed, like you mentioned. I did not check the skin, but rather noticed how clear is eyes seemed, and have heard of the eye pieces getting stuck during a shed. I thought perhaps it could happen the other way around.
He takes a few weeks to shed sometimes (which I've heard is normal and abnormal from various sources), although his eyes generally do not look real cloudy until 1 to 2 weeks before the acutal shed. He has a fairly large water bowl, but he isn't very fond of the water (the temp should be okay, I played with the location of the lights to heat it up more because I thought it might be too cold for him, but he still didn't seem to use it much, except for drinking) so I started soaking him myself, prior to sheds.
I generally keep the humidity around 55 - 65 percent in his cage. I have sprayed his cage down, in the past, but it didn't seem to work nearly as well as just soaking him in the bath tub for a few minutes each day before he sheds. Also, I am using shavings for substrate in his cage (which I think I am going to replace with newspaper, like I am using with my ATB) and I wanted to avoid peaking the humidity too high and ending up with wet shavings, harboring bacteria. Maybe this is a bit extreme, but it is sometimes easy to miss stuff spot cleaning, and I have heard all kinds of horror stories about nasal infections, etc, and I really don't mind bathing him for a few minutes at a time.
Thanks for the feedback.
