Polish knowledge needed!! Roos or hens?

[LN8]

Ok, so we live in town and I acquired three Polish (and some others) chicks and while the white crested one has “crowed” the other two have not but I’m going the feeling that all are Roos. I brought them home from Wilco as “Polish Bantam Assorted SR” on January 22nd. Any help is very much appreciated.

Please let me know if better pictures are needed.
First set - white crested
Second set - silver laced
Third set - black

The black is definitely a cockerel. The first one you already know about. Not sure about the middle one

Thank you! The middle one doesn’t act the same as the other two, it’s quieter and likes to hangout with the smaller chicks.
