Do Wyandotte’s grow extra slow?

I got a shipment of chicks on the 11th. And at this point all the other chicks look like they are a week older then all the Wyandotte chicks, if not more. Even the other smaller chicks have more feathers.
I’m curious if this is a breed trait? They are all active, healthy, and I have multiple feeders and waters. So I know everyone is getting enough.

No, slow growth is not a breed trait for Wyandottes. What are the breeds of the other chicks? Maybe they are breeds with rapid growth.
