Normal color on the 1 Polish[weird brown]?
Genders?
Guessing the Wels w/blue is a roo.
I can't tell you the age, but the Polish are...2-3wks younger than the Wels.
The polish look like pullets. By wells do you mean welsummer? Those are Blue laced red wyandottes....
The one on the top left in the last pic is a boy and rest are pullets
Top Polish is a pullet and the one next to her could be a pullet, not sure, but the other is a roo. I had one whose crest looked like that one and everyone told me Pullet but it turned out to be a roo. Sometimes it's just hard to tell till later.
