I'm actually not sure! I really don't know much about quail! I bought the eggs off of e-bay and hatched them. I'll crack some open when I get home.
Ohhhh...I was under the impression that these were your quail eggs, from birds you already had. That's odd then, if you bought and paid for fertile eggs then they should be fertile. I don't much about quail eggs myself either and I'm still new at hatching so I wouldn't be much help there :-(
