Hi Matt,
Hard to say whats going on with your new iggy but first make sure he's not near the girls.
I would then try and clean his eys with a cotton ball/ warmish water, and get him set up and see how he does as far as basking, eating so on. May be parasites/may need to have a fecal done on him. The eye goo may be from being in the dark container, but watch that also. Sometimes messy sandy eyes can be a sign of a respiratory/bacterial infection.
I would also let the person you bought him from know that these are things you saw when he arrived, and will keep him updated as far as his condition. Just so he knows you got him like this incase something were to happen or for medical purposes.
I sure hope he will be okay, and he's just a bit stressed, let us know. I have had my iggy for atleast 4- 5 years and never dealt with that...
