I'm pretty good at sexing older barred rock chicks, but it's the tiny babies that I can't get. I know females are darker, have a darker leg wash, but I can't figure out the headspots. I don't want to wait till they're older to find out the sex - if I accidently picked out a roo, I'd like to know as soon as possible so I can return it for another the same size (we aren't allowed roos here). The feed store I purchased these chicks at only sells chicks sexed chicks (at least they try). This first chick is the one I'm most questioning. It's about 1-1/2 weeks old. While at the feed shop, I tried picking out the darkest, but they all seemed the same color to me and I couldn't remember the headspot rule. Even after looking it up, I can't figure out where this faint spot fits in. Also, this chick has a light colored tummy that I didn't notice at first - the younger chick is all black. Very faint head spot/line: With a flash: Same chick without the flash; Close-up of legs: Chick #2's head spot -- less than 1 week old: Chick #2 has dark legs - darker than chick #1. It's also blacker in color, but maybe that's because it hasn't started barring yet?
