Well, the spike happened when these eggs were no more than 5 or 6 days into the incubator, so I strongly doubt that affected her pattern. Especially since her brother has an identical stripe. Their mother Toki has a little bit of a stripe thing, and their daddy Yakul has a tail stripe. So I think it comes from mom and dad. The banding was unexpected, but the great thing about pieds is the funky pattern, so who knows where that came from.
