Is this normal for a Polish?

[EmmaRainboe]

Hello!

We recently got two straight run Polish, they are 6 days old and seem so small compared to our other 6 day old chicks. We have never had Polish chickens and so I'm not sure if they do usually run smaller. My other question is we noticed that on one of them the wing feathers are different and have a curl to them. Sorry the pics are not the best. They are very active lol. Does this give away if they are a pullet or Cockerel? I know it's super early. Could it be that it has a frizzle gene? I just want to make sure it is nothing I need to be concerned about or that I have to do something.

The white one is the one with the wing question if you can't tell.

Also, would anyone be able to tell me what colors these two would be classified as?

Polish are just smaller than most standard birds.
