Because both the piebald genes and the albino genes are recessive, you would get babies that appear normal but are het for albino and piebald. If you are wanting to sell babies that look albino, piebald, or albino piebalds, you will need to keep those normal het albino/pied babies and either breed them together (if you want albino pieds) or breed them to either the albino or pied for albino or piebald babies.
