Sexing Silver Pheasants??

[Orpimom]

I hatched out 4 Silver eggs a friend gave me and sold 2 of the babies.The two I have left are probly a couple months old. To me(the untrained eye) they are identical except one is probly 3x the size of the other. What could I look for as far as trying to sex them? They are both starting to get the bright orange around the eyes.The larger one is more tame than the smaller one.I raised them in a tote in my bathroom for the first few weeks.The one got to where it would jump out and follow me around the bathroom and actually scratch on the door to get out.He peep peep peeps at me all the time.Even now since I've put them outside and have had less interaction it still peeps consistantly at me.I will try to get pics later.

You have to wait until they are about 9 months old.These will look like hens one day and males the next.
