They do look different. Were they from a hatchery? Rare for them to make mistakes with sexlinks, and you're right, it would have to be a different breed... male would be barred.Hi. I got what I thought were 2 black sex link chicks. They are developing feathers in a very different way. I’m worried one is a Roo of a different breed. They are 5-6 weeks old. Thoughts? Dolly has the larger comb and Dottie has a more developed tail.
Thanks

Think you can be pretty sure the one with the small comb is a female. The other sure has thick legs and big comb by comparison, but if they were mine, I'd wait another week or two to be certain... see if that comb keeps growing and turns red. You might just have a hulking pullet. Let us know how it turns out.
