Have you ever had a neighbor suddenly switch up on you? @cooper.john, I feel your confusion because mine did the same thing. I just started taking out their trash bins by mistake and then chatted about the local sports team. Sometimes paying a little attention to the small stuff is all it takes.
The part nobody talks about is how a quiet rooster changes the entire morning vibe for the neighbors too. Once their sleep stops getting wrecked, they probably realize you're not the enemy and actually want to hang out now. Did your tweak involve something like adding a dark box inside the coop or was it something else entirely?
