HELP me sex my chukar

[NSKDodge]

Why is this so difficult? Maybe someone here can see what sex my little birds are... Chukar #1 is the more petite one, the body and head are smaller but it has little bumps where spurs would be. Chukar #2 has a larger body... more block headed but zero spur bump... I asked the vet and they say to have their blood tested would be $100+ EACH.

Number 1 is a male for sure.The spur is the easiest way to sex them.Number 2 looks to be a hen,but you said his head is more blocky,this is another sexing method which is a male,but no spur?He should still have a spur.i guess you'll need to see if you get an egg.
