I got the BJG is a Black Jersey Giant. EE is Easter Egger. Is a BA a Black Australorp?
So the loudest is the Jersey Giant?
I’d say the Dark Brown leghorns were loudest. They had the ear-splitting note in their crow - more annoying and carried farther it seems. The BJG is loud, but easier on the ears, plus less crowing overall.
All acronym assumptions were correct!
