Hello, I have a quail pen 5' L x 3' W x 2' H. I have three questions: 1) How many Bobwhites should I purchase and not have issues w/ space? 2) Plus, how about ratio? Example 2 males & 2 females? 3) Are Bobwhites the same as Coturnix Quails with 1 male w/ 3-5 females? Much appreciation and thank you!
