I have polish about the same age. Yours looks a lot like some I have & I am wondering the same thing, so I'll post mine on this forum too, see if folks can help us out
Definitely a roo..I have 2-10 week old- white crested black polish one is male and one female and the female has no redness or waddles on her face thats how I can tell.
Thank you for your response. Was of course hoping for a girl and it would have been my only white egg layer...but I will take him anyway, he is such a joy to watch!
