Raising Polish Chickens

[Dragron_ heart]

This year is the first time I have attempted to raise a flock made up entirely of Polish chickens. I have several chickens that looked exactly alike. It is amazing, but they are absolutely identical. The chickens are straight run so surely I have some roosters. The problem is that, unlike standard chickens, they seem to have no differences that show the difference between male and female. I only want one rooster in the flock, but if I can't tell them a part I can't separate them. Does anyone know of any thing that can be seen to separate the roosters from the hens?

How old are they? Hens should have a neat, round crest while the rooster's crest should be stringy and wild like a rock star.
