>>What?
You asked "is there an issue breeding Kahl line Albino x Albino?"...
There are two types of albino boas, there are kahl albino boas and there are sharp albino boas. By saying "is there an issue breeding Kahl line Albino x Albino?" you are basically asking if there is an issue breeding an albino to an albino, because without saying "sharp albino", "albino" is pretty much saying you have a kahl albino, kahl being the original of the 2 albinos.
The kahl strain albino and the sharp strain albinos are not compatible, so breeding the 2 will NOT make any albino babies, just hets. Breeding a kahl to a kahl or a sharp to a sharp will result in all babies being that strain of albino.
