Wyandotte Comb

[denanner13]

One of my Columbian Wyandotte babies is developing what looks like a standard single comb. All the other babies aren't showing much of anything, which seems normal for a rose comb. In every other way she looks like the other Columbians. Any ideas what may have happened with her?

I read that the Columbian Wyandottes will occasionally have a single comb. A few of the chicks we bought have them, too.
