This Black Crested White Polish is 12 days old and seems to act like a roo. Is it possible to sex a Polish at this age? Do you think it's a roo? In the second photo he/she is the one on the right.
My best guess at this age is Roo but then again I'm still trying to sex my 8, 2 month olds! I can't wait to see a black crested white when it gets older!
