What do Bielefelders hens look like?

[JedJackson]

I think what the poster is getting at is that the barring isn't very apparent in the females in the original photos compared to some. But that is probably just variation.

False, false, false. Bielefelders are an established pure breed, not hybrids. They breed true, and if they were all purchased from the same place they should look the same.
The lighter one is a male, not a different breed/strain.

Ok
That’s just what I saw on Wikipedia, your explanation makes sense

Ah, they are young yet. My Bielefelder girls grew in feathers with more distinct barring after they went through their puberty moult. Lilli is about 5 months old in this video.

The lighter/brighter ones are males.

They are their own breed now, with previous contributions from the four breeds mentioned in the article.
