Generally polish males have a wild rock star crest and the females have a tamed rounded crest. It's not a perfect way to sex them but, it could give you a clue. Welcome to BYC, polish are such attractive birds, especially the laced ones.
Welcome to BYC! Glad you decided to join us. Mountain Peeps X3. Based on what little I can see in the pic, the one on the right looks like a male; the one on the left a female, but I would need a much better picture to be certain. Please feel free to ask any questions you may have. We are here to help in any way we can. Good luck with your Polish.
We'll need better photos to tell the gender of your birds. However, I'm leaning towards the bird on the right being a cockerel, and the bird on the left being a pullet.
