First of all, the albino, as Weasel said, is probably already neutered/spayed. Secondly, he should only be taking the ferret if he wants it as a pet, not as a possible money maker. And lastly, I doubt there's much promise in it. Is there much demand for ferrets in the area? Then you should encourage adoption. The number of ferrets up for adoption is absolutely INSANE it's so hugh. I'm looking into that right now. I was expecting it to be challenging.... hah!!!
Aside from the preaching of this that and the other, like Weasel said, if it's a beginner then he shouldn't even be bothered with breeding! Wait til he finds out the responsibility associated with just one... not to mention cost of shots, spaying/neutering, descenting, finding a reputable TRUSTWORTHY vet, bedding (I recommend a paper shredder), etc...
