I have 2 Chukers I raised from chicks. I don't even know if they are male/female or not, but they like each other a lot. They hang out in my quail pen and seem pretty content, altogether. The enclosure is a decent size. I'm hoping I have a pair that will mate, but I don't know how to tell them apart. One looks a little bigger/fatter, but that's the only difference I see. No eggs yet either.

The different subraces of Yemenite Rock Partridges blend into one another-some flocks will include two or more of the colour morphs, though this is uncommon.
In captivity, the Silver morph has become more common than the Northern morph. I don't know if the Southern dusky morph has ever been kept in USA.
