Last year I had a clutch of 7 eggs from het albino to het albino and not one albino. I am keeping all the female babies to breed to another het albino male when they are big enough. I was going to keep them all and breed back to dad but. Picked up another het albino male. They are so cheap right now so figured why not. Then I dont have to breed them back to dad. Not really an answer to your question. But my point is you might just have missed it with them. I would keep them and get a few more clutches out of them before you write them off as just normals.
