Okay, so are you wanting your Willie hens to hatch them, or are you wanting to raise them yourself?
Quail chicks require a little more cautious care than baby chickens. They are very sensitive to heat, prone to drown, etc. — not to mention that they require a higher protein food as well.
If you are looking for a bird that will reproduce on its own (lay eggs, go broody, rear young), I advise against quail.
If you are looking for a bird that grows quickly and look unique, then quail are for you. I have raised quail for a few years, but only coturnix quail (the pharaoh variety). They make great meat and egg birds. Button quail on the other hand are very, and I mean very, small birds — but they do make fairly good pets.
I don’t know how much of a bird enthusiast you are, but if you’re looking for a bird that makes a great pet, I would get geese. They are very intelligent and usually bond with their owner if raised from a gosling — just an option.
