Is it normal for Turkens to be this large at 4 weeks?

I have been looking at the new pioneer broilers. Three hatcheries are selling them now. I do believe that is what you have.

Thanks - I've gotten a lot of feedback, and done a ton of research. Even if they are Pioneers, those have been crossed, and bred to have stronger bones & legs, and develop more slowly, and be strong enough to continue to mature and lay and breed. An actual pioneer person (or homesteader) wouldn't want a fowl that can't live long enough to reproduce - where are you going to get more chicks?
Regardless, the way mine are developing, I don't think they are anything but standard Naked Necks. Thank you all - your input has been important to me.
