Is an albino cockroach rare

Yes, albino animals are rare period. My white face and normal grey cockatiels just hatched 3 chicks. A normal grey, a white with dark pupils and a white with red pupils. I have heard that the latter are just white lutinos with red eyes. But after speaking with my avian vet, he explained that it is possible for all species to have albino counterparts. I wish I could upload a pic. But, they are not unheard of. google images presented many albino tiels, but of coarse the albinos are not an everyday occurance and they are very special.
