Don't know about expert but here is what I believe to be the facts...Friday.
If they are native species you are supposed to have a license (Bobwhite, blues, and ringneck pheasant (these aren't naive but apparently got adopted)) The other colored bobwhites don't count (red, white, Mexican speckeled)....for the ornamentals you don't have to but they are considered to be upland game birds. BUtton quail and coturnix do not count. In order to have like bobwhites and release them you have ot have a license that shows such and such and mainly means you have healthy stuff or get it from healthy breeders.
They do not do alot of checking on these birds so it is basically a hit and miss sort of thing when it comes to enforcemet. As long as you are not releasing them you are gonna be okay...opinion here!
For me I like trios or quads on quail and pheasants. They need flight room and cover. The yellow goldens, reeves, and such are roosting birds and will need some limbs and stuff...a covered area like a dog house works for a nest box...with the pheasants size depends on tail...the bigger the tail the bigger the enclosure...around 4ft wide...10 ft long and 8 ft tall for a pair or trio is about right on the smaller birds...you can put birds together in a group setting but you gotta start using blinders and such with the cocks...you can grow them out in a large area...you want to provide protection from wind...typically folks put tin around the bottom...about 2 ft high. then good netting over the top to stop escapes and predators
feed runs the spectrum...game bird feeders to scratch feeders to special blends...protein is of key importance...in the wild these birds ae taking in insects aswell as grains...they typically need a higher protein content
