Introducing my top hat chicks

[PhunneFarm]

hi so I'm just wondering if anyone can maybe tell the sex by looking at them so far. Advice would be much appreciated. Thanks!

I thought they were the same bird at first. Is each picture a separate bird? Are these mottled houdans? How old are they?

 

[PhunneFarm]

Yes they are separate. I honestly have no idea what they are. But at least a couple months old.

My guess is that the 3rd and 4th to last down are roosters but it is hard to tell. They almost look like all hens.
