Give it a try. Your snake will tell you soon enough if it's too big. I would say it should be able to eat that.
As far as the eye goes, keep inspecting it and see if it gets any worse. I'm not sure what you see, but I don't see anything out of the ordinary. As far as paradox, only time will tell. You will have to breed the snake and see what the babies look like. Anything is possible.
Good Luck!
