The bigger the pen you can give them the better.
I know some people may be stuck for space but its better to give one or two pairs a decent size rather than trying to keep 5 pairs in the pen of the same size.
Some of my pheasant pens are 30ft in length.
I keep Himalayan Monals, Koklass, Temmincks Tragopan, Cabots tragopan, Elliots, Blue eared, Reeves, Reds, Yellows, Amherest, Silvers, Cheers, Bornean Crested Firebacks, Indian blues, Whites peas.

Aviary size is important to most species if they are to breed successfully, In the case of the smaller species, such as the golden pheasant, a minimum size of 3m long by 2m wide, plus a shelter 1m deep by 2m wide, will satisfy one pair and for the larger species, the minimum should be double that size. The Aviary should be at least 2m high to allow a person to walk around, the sides preferably, should be covered in galvanised wire of 25mm mesh, to keep out sparrows and other vermin, with at least 15cm sunk into the ground and a further 30cm coming out flat at right angles underground. This prevents rats and other mammals digging under the netting.

A friend of mine in Ireland has probably the biggest Pheasant set up in Europe.
He has every thing from Argus Pheasants to Malaysian Peacock pheasants and his pens are big which gives him better results.
