Seems strange to me, I have three roosters in my flock of 20 birds two EE and one Guinea hen, and have yet to here one cockle doodle doo. I have tried demonstrating....and they all run. The last batch I had it was a constant contest, and got me turned into the city zoning enforcement. Has anyone experienced this? I mean the lack of crowing, not being turned in to the city. Just wondering.
