6 week old cochins

[Cinnamon11]

I have two 6 week old cochins and two 5 week old chicks a wyandotte and Olive egger. Any idea on gender?

I'd expect all to be pullets. The only one that I would watch is the second cochin with the red wattle growth but it isn't enough to make me fully think of cockerel and not pullet.
