Lol, compared to turkey toms they are all quiet. Luckily I have neighbors that love to hear my guys gobble.
I have EEs and Cornish Xs at the moment. Just gave away a Polish roo. The EEs are not what I would call noisy, but they do get riled up easily and get a bit squawky then and at feed time. I only ever hear the Cornish when it is feed time and I am five minutes late, lol. The Polish was a talker. He was the spokesman for the EE chicks when they were little and he thought they should have dinner.He is a cute little guy. Gave him to my daughter because I intend my EEs to be a breeding flock and already have EE roos.
Edited to reply:Of course Cornish Xs are short-lived, so wouldn't be a consideration for backyard flock, really. These guys are destined for the freezer. Just making an observation about their noise level.
