Pullets or Roos: Cochins and a Houdan

[ecstasis]

I have two partridge cochins who are about ten weeks old. One is growing much faster than the other but both have waddles and large combs. Are they both roosters? I also have a mottled houdan that I got from a straight run. S/he has a really long tail so I've suspected possibly a roo. Nugget (the houdan) is about three months old. No crowing from anyone yet.

I think Nugget is a pullet and the other two are cockerels

My guess with the partridges is a pullet and a cockerel. In the last picture, pullet to the left (brown color) and cockerel to the right (black with brown hackles)

Both Cochins are cockerels. I’m leaning cockerel on the Houdan as well.

Your Houdan appears to be a pullet. The Partridge Cochins are almost certainly cockerels.

As a footnote, are you certain that the first bird really is a Houdan? I thought they had beards and muffs.

To complicate things the cochin on the right in the last image (mango) is a really slow developer. S/he didn't have feathers at all for the longest time after Harriet (cochin on the left) was already fully feathered.
