Actually, if I recall correctly, in the early sixties there was a time with a limit of five and one could be a hen. Back in the soil bank days. Lots and lots of birds.
I remember those days! Seems like there was a state hatchery and a brooding center in Capauldo, Ks. (sic). When I was there they were raising golden pheasants to introduce in SE Kansas. I used to see them around, but they didn't survive past the couple of years. But quail were everywhere!
