Yea, I understand that- even though its not right.. But there is a few people on there selling gravid snakes that they say that they bred themselves..
Heres one with an supposed 'het albino' female to an 'albino' male: http://market.kingsnake.com/detail.php?cat=32&de=564149
So if he really did breed his het girl to an albino, why wouldent he just keep her at least untill she laid the eggs? I dont know- to me it just doesnt make sense
