I have often heard about regs that forbid the taking of albino game, yet when I've looked into it I have not found it to be illegal anywhere. In PA the game commission addresses albinos in their hunting publication, they say to go ahead and shoot them for they usually are piebald and if actually albino have a significant chance of not surviving long on their own..
Most white game animals are not albino but just white. True albinos are usually nearly blind and often shunned by their own kind. Don't know how they could be protected since you will only know if it is an albino, and not piebald or white, when you can clearly see it's pink eyes.
They are a genetic mutation that does nothing to improve the species. Most birds that are white are usually not albino but just have white plumage. For those that want a mount, get your animal bleached and colored white, don't know if they can bleach and color feathers white though.
