can anyone tell me which of my chicks are hens

Try getting multiple pictures of each chicken
Front picture of comb/crest. Side picture of head and/or side picture of whole body.
Need to see if there are streamers in crest/neck/tail, comb/waddle size, and stance pretty much!

How old are they?

In the first picture, the very front chicken, 98% sure that is a rooster, going by the comb size and prominence of waddles. He reminds me of my white roo in the crest too.
Other ones, I would need to see better pictures to state my opinion on their sex.

 

I eagerly await more pictures of your cuties!

 

I think the white one is a cockerel. That stance is really high- I've never seen my pullets stand like that, but my white roo and splash roo have. Having a little trouble with the other pictures because they're out of focus. I'm trying to look for streamers and whatnot, but I can't see them

In the bottom pic, the one on the far right might be a pullet, her stance looks pretty low.
