I might make 2 breedings of siamensis this year. I will definitely try making the same first breeding as last year. That produced some very high-white hatchlings. The other female I bred last year, doesn't produce many high-whites even when bred to a very high-white male, so she is retired now. She is a CB'99, so she can just out her life now.
I do have a couple more high-white females and a couple high-white males from several different lines, but I think I will just pick one other female to try so I don't end up with 200 siamensis hatchlings.
