This is the first year I've raised a large number of chicks. One thing has me puzzled - I get three basic juvenile feathering styles in my silver duckwing chicks - dark/mostly black chicks with prominent combs (roosters), white/silver headed and chest (pullets) and then I get ones that look like a pullet in all respects (white chest, minimal comb) but have a black head. It's these last ones that have me puzzled. I think they are cockerels, just perhaps less flamboyant ones. But I'd like back-up opinions. This photo is of roughly 8 week old chicks, all from the same batch. The far right you can see the clear rooster - left under the hen is a pullet, and you can see two of the black headed mystery chicks. My gut response is that the darker chicks will end up with better feather as adults - both male and female (I do have one pullet that has a lot of black on her chest compared to the others). I'm very curious to see if this is correct - input is welcome.
