I've had blood rings a couple of times before, those just happen, but the infertile eggs would be quite the disappiontment, did they guarantee fertility? Because then you should definately get at least a partial refund, sellers need to be checking that sort of stuff before they sell hatching eggs. I don't want to complain to my seller because she seems really nice, like she really cared about these eggs even though it wasn't a smart idea to ship them over Labor day weekend. If the remaining 4 manage to develope, I'll be happy, but with the whole labor day thing, I'm not so sure they will and $40 is a lot for absolutely nothing. Crossing my fingers for your remaining 3 eggs!
