I ordered from them once and had a very hard time with communication. I sent a bunch of emails and never heard back either. I wanted to know when they were sending the cuttle eggs i had ordered so I could make sure I was home when they arrived, well two weeks went by and I came home to a package on my door step. When I picked it up it was 100 degrees from baking in the sun all day. needless to say the eggs never hatched.

Are the eggs WHITE by chance? Are the round or oblong?
Are you hearing a thunk like the movement causes one of the eggs to hit the side of the container or just being ... funny. If you are seeing actual movement can you catch it on video by underlighting the eggs?
