Just witnessed something weird...

[AJ666]

I was sitting in the grass watching my flock in the run and all the sussen my EE Big Girl made the chicken alarm call. Then the whole flock froze in their tracks, not moving a muscle. All the sudden one made this high pitched purring like sound. Then another one did it. Then another. Pretty soon all my chickens were standing around making a chorus of long purring sounds! Then, the EE who made the alarm call whirled around and raced into the coop. The rest then followed.
I looked into the coop to see them all huddled in one corner, not moving. Something scared them, but I have no idea what it is. Maybe a hawk?

Yeah, they probably saw a big bird. They make those purring sounds so everyone will freeze and be on the alert.

mine do kinda the same when the Eagles or Hawks are around. The roos scream and then the rest then they run for the trees.

 

[HennyJenny]

Mine do this for airplanes and helicopters

They can't understand why I don't do it to.

A few weeks ago I was in the backyard when a pair of bald eagles circled over my yard. The chickens and cats disappeared without a sound. It was eerily silent until the eagles left. But the will scream and raise a ruckus if a small bird or bee or leaf passes overhead.
