Hoping for hens...?

[Rustyjunk71]

About four weeks ago we got these three chicks. We are hoping for hens as we can’t have roosters where we live. Any ideas? Also the feed store marked them wrong I think. One was marked polish. I think they are bantam Cochins and a buff Orpington thoughts? This is our first go at chickens...

The brown and white one is a Red Sex-link pullet. The black one looks like a black cochin bantam and seems to be a girl so far. The brown one looks like a partridge cochin bantam, and is most likely a boy.
