I'm venturing to guess pullet on the polish. Because of the coloring, and I don't see any wattles starting or red to the face at all. They can be really tricky at this point though, so I'm offering a 50% guarantee
Best time to sex is at a day (by the shape of the crest). After that they start to really change. I have one that I would've swore up and down was a roo (looking at the crest while it was growing out), but is actually a gorgeous little pullet with a HUGE crest!
