I learned that lesson this year myself. I had my pick female a BEAUTIFUL normal female who I got as a baby 1.5 years ago. Was cleaning cages and thought heck I will just put her with my big female for a second and when I went to get her less than 5 min later I found them LOCKED. I about died. The large female is my poss het albino and I had her paired (and seen a lock) with my het albino male. So my luck I will have an entire clutch of normal babies that I will have to call normal babies unless (hopefully) one is albino

Two lessons learned sex them and don't get lax on keeping them apart. I knew both of them to be healthy (I have had them both over a year) so I wasn't that worried. Now I am paying for it.
