Hi, I am looking for some help. I started my second flock of chickens in June, ordering from a different hatchery this time. Of the 12 pullets I ordered, 3 are definitely roos and the three silver laced polish don't look much different from my old silver laced wyandotte hen. Can anyone tell me when Polish generally get their crowning feathers? They are all 14 weeks old now. Thanks for your help.
