I’ve read so many articles … I’m still torn on these guys. I think purple may be a hen!? Teal looks to be a roo. Not sure of the red collar and no collar. These silkies are 16 weeks old. No crowing. They all still face off with the hens and each other so - I can’t really use that behavior as a clue. No fighting. Teal has some wattle. … clearly a first time silkie owner. Forgive me!
