Hi there, we picked up 5 chicks from a local farm last month. They are now around 4-5 weeks old. I have no clue what breed they are, one looks like it could be a barred rock. Also one of them is displaying shiny feathers and just now when I caught it, it lifted its neck feathers! Is this a roo? I'd be happy if you guys could help me out Barred Rock? the roo? All the brownish feathers around his neck where lifted when it seemed upset.
