I do so love the pics of the babies!!In addition to brittle feathering, double-frizzle-gene 'frazzles' also have enlargement of the heart, rapid heartbeat, and malformation of adrenal and thyroid glands, all likely caused by the higher metabolism that these birds have and generally leading to shortened lifespans compared to even single-frizzle-gene birds. It's really, really not great to breed two frizzles together.
Terribly sorry to hear that! I know it's not the same, but I'm sure there will be many pictures to come for you to enjoy even if you aren't able to get chicks of your own.
