Hi, Im just curious about how big the normal home range of quail is? How much land would be needed for good quail habitat? I have a 40 acre section available that is mostly pasture and very few quail, a 20 acre wooded mountainous spot that I have never seen a quail and a 10 acre section where I have seen numerous quail this fall and winter. I guess it depends on the surrounding lands also.

So any ideas on how big their natural home range is?

Thanks
