I had this Red Golden Pheasant chick that was a yellow/white colored, as opposed to the brown/dark brown coloring of my other chicks. I assumed this meant it was a girl, since last year, out of the two who actually hatched, one was the same yellow/white color. Both chicks died after a freak incident. But this year, as more chicks have been hatching, I've noticed they're mostly so-called "males", in that they have a brown coloring. I got curious and looked up how to sex a pheasant chick, and the sites I looked at only mentioned eye color, they never mentioned this obvious color difference. Below is a picture of the chick with it's siblings.
You can clearly see that one is much more yellow than the others. Why is this? Unfortunately, the yellow chick died after getting her legs caught in the cage's wire floor(apparently pheasants are so leggy that they tend to get their legs stuck in the wire spacing after sitting down!), so this is the best picture I've got. She had white marking where her siblings have the dark brown patterns. She's definitely a Red Golden and definitely a pheasant.
