so my babies are just under 4 weeks and I am suspecting that 1 of my blue cochins is a roo. 
It is one of the friendlier chicks noticed yesterday that the comb was looking pretty pink, seemed a bit more "orange" today but not pale like the others, has a hint of waddle unlike my other blue cochin that has none, slower growing tail feathers but it was the one that started to feather first and has more back feathers than the other one has. But the one in question has what I think are thinner feathers. What do you think??? not the best picture but both are pictured here. The one on the right when looking at the pic is the one I think is a roo.
