For transportation crates and other supplies https://cutlersupply.com/zen_new51/
. Unless your pheasants have binders no way should you put with other birds. Even with binders your taking a risk, they are very aggressive. In certain transport crates they can be together if real low, just for transportation. In transit or in these crates they produce a lot of heat, so keep them cool or they will die, also keep them hydrated, plenty of water and some fruit, if they will not drink in crate oranges apples. Like was mentioned these crates are for transport only, they are very confining, not humane if used otherwise. Also which was mentioned, if kept very long diminishes good flight and can cause serious set backs in training.
A small but effective pen can be constructed if handy. 4'h x 4'w x 8'l about 3ft off ground. Use 1/2 inch hardware cloth on 2x4 joist for birds to walk on a crap to fall through. I use the cloth below as well leaving a 3 1/2 inch space this stops predators from eating feet or legs. The roof is flat use 2x4 rafters top use metal roof, bellow or bottom of rafter use 1/2 cloth. This keeps birds heads from hitting the steel roof, and unless they hit rafter gives a little cushion without getting head caught in netting or chicken wire. Ends are a piece of plywood cut in half. One end you will need to cut a door into it and attach hinges. To keep door from going in a door stop with 1 x 3 for strip screwed to side of frame. 1/2 inch hardware cloth on side of pen attach to rafter on top, attach bottom to joist on bottom. On the ends 4 corners 2x4 upright, allowing for legs and to attach plywood ends. Also is header going across on top for rafters to sit on and the bottom for the joists to sit in. Because top heavy use an anchor screw into ground both ends and attach cable and binder. I keep east side open to weather other side tarp. Holds about 50 quail or chukar and even a month does not seem to effect flight, I believe they fly or flutter around in the cage, when alarmed. I lost a couple think they hit their head on the rafter, but not sure and can not tell you how many over the years were used. Had waterer heated in winter and several different feeders depending on the bird.
