I haven't noticed that they're more vocal. They're pretty vocal all the time, always softly talking to eachother. They do get more edgy, more on alert, readier than ever to run, and they stay closer to the bolt holes to their runs when out. They hear a big windy breeze coming before I do, stop what they're doing make for safety.Does anyone’s chooks get particularly vocal when it’s really windy? Mine seem to, although it’s anecdotal.
I think they can't hear the usual warning cues from the variety of forest & old orchard birds and animals, which at least here is the early warning system for anything untoward. A couple of days ago I heard one of the signals, it made the Buckeyes stop, freeze for a millisecond and quickly get back to the closest run. It was a single, lone, very high and very soft whistle, lasted about one and a half seconds, and they had started to move before it was over. I don't know what bird made it. Sounded a bit like a chickadee's voice. A chipmunk had been barking which they didn't change behaviour for, but this thin little whistle in there did it.
