Don't know if this is just a roo behavior. They are 12 weeks old and I've noticed them both doing their little "dance" with their neck feathers ruffled up and hopping and sort of bumping chests. I have a stinking suspicion that at least one is a roo. It has a "fluffier" sort of tail feathers with one curling down. However, the comb isn't even pink and is small. Haven't heard any crowing other than the daddy yet.
