I think your hypothesis needs to be more refined, you'll need a large sample, and you'll want to do some other additional research first.
It's not that you will never have a broody quail, it's that they usually don't. And that is usually how it is described, not with the "never ever broody" statement.
Excellent post, @purslanegarden ! I assume he needs to complete this by the end of the school year, though. Unless he could get full-grown laying quail pretty much immediately, it would be pretty tough to do even the most basic study in that time frame, not to mention evaluating the data and writing the report.
