If they are from the same clutch of eggs I would have to say the green got the crappy end of the gene pool, that is a huge difference. Did you breed them yourself or were you just told that they were from the same clutch? Because if you were just told this the person may have just told you that and didn't know what they were talking about and they are from 2 different clutches. those are the only 2 things I think of off the top of head.
