What beautiful babies! The only trouble I see is that you won't know for sure whether the stripes are homo or het blood without test breeding them, since the parents are normals. I have 3 striped males with a bloodred father I need to prove out myself.
If both parents of these kids were proven bloods, then they would definately be bloods.
If I were you, I would keep back all the stripes, and get a few bloodreds with no striped gene in them to test them out. If the resulting offspring are 100% bloodreds, then your stripes would prove to be homo blood.
