Crow less Rooster? Have you heard of it?

[Feathers of Eden]

I read from a thread in 2009 Bluegrass Seramas from Kentucky had a line of seramas that squeaked rather than crow. I think it started with this rooster of hers

His sons also had a similar crow. If only squeaky seramas were more common in Canada.

I think there is a viable market for selling crow less rooster specially if it is dialed after a few generations and breeds true.
