There is no such thing as a het normal! A Pastel to a normal would get you 50% pastels and 50% normals. If the normal was a 100% het of any recessive morph then all babies you be 50% hets but if you have a 50% het, you can't say the babies might be het because you don't even know if the 50% het parent carries the gene or not. I hope this answers your question!
In that case I believe it is 50% normals and 50% pastels all...and correct me if I'm wrong someone cause I'm bad at math...33% het hypo...which doesnt mean they have 33% of the hypo gene, it means that statistically 33% of the hatchlings would carry the hypo gene.
The 50% het hypo does not factor into the equation because it may not be a het at all! You need to breed the 50% het hypo to a 100% het hypo or a hypo to prove it out as a het! Since you don't know if the 50% het hypo has the hypo gene, all you can say is that the babies are pastels and normals.
