Red Footed Tortoise Problem

[Bighead]

We just got a red footed tortoise at the store I work at. He's in a 40 gallon tank right now, he (or she) is about 5 inches long, The humidity is a little above 80% and temperature is in the upper 70's/lower 80's with a basking spot in the high 80's. This seems to be ok according to the caresheets I've read on them, and we've only had him for 2 days, so I'm assuming it's nothing we are doing wrong.

The problem:
I'm not sure if this is normal or not, but when I pick him up, he bobs his head fairly quickly. It just doesn't seem right. It may be my imagination but one of his eyes also looked a little weepy. It wasn't swollen or discolored or anything, but it looked like he had a couple of little tears below one eye. It may have been from his water bowl or something, but thought I should check just in case.

Thanks for any input.

P.S. Is it too early to tell what the sex is? If not, how do I tell? Thanks.
