I would say that unless you bought a 100% het pair from the same breeder and you have 3 clutches with no visual morph then you should get a refund. Breeder should not be be responsible if you get your male and female from two different breeders because you don't know which animal is the problem. I don't think the breeder is responsible for the feeding, caring or future clutches, that is the gamble you take with hets. If you go the cheaper route(hets) then you are taking a chance! If you want a 100% guarantee then buy visuals! You pay for what you get!
