You should be ok with the 2 pens you have until this time next year. Then you will need an aditional pen for each male and his group of girls. The males fight like crazy when breeding time comes round. If you have a large enough pen you might get by with a couple of cocks in one pen, if you have enough hens to go round. Still better to have them seperated. That way there is less stress on the birds and your fertility rate will be much better. My avatar picture is one of my Lady Amherst male pheasants. I raise mostly Ringnecks for several local hunting preserves but also have Yellow and Red Goldens, Lady Amherst, Silvers and Wild Mallard ducks. Goldens are easy to raise and care for and If you've had the experience with incubation you shouldn't have any problem incubating the eggs. Spraddle leg is a lot more common in pheasants than chickens so you might want to make sure you have your chicks on good footing right after they dry off in the bator. Will try and get some more pictures as soon as I get a chance.
