Can hens REALLY crow?

Yes! It's not even that rare, either! In all-female flocks, or flocks in which the ratio of females to males is greater than 10:1, in many cases one female will take on male characteristics and become the "protector" of the rest of the flock. In addition to coming out with a half-crow, she'll usually cease laying, and she may even develop spurs to rival a male's. Strange, but true!
