Once when I went out to see the girls, they at first acted like they always do(crowding around me looking for treats). I was out there for a little while taking care of some stuff when i noticed all my chickens standing as still as statues. I've never seen this before and even when i went over to them they still didnt move, and stayed like that untill i reached down to pick one of them up. They acted normal again but they would occasionally stop and stand still for a minute the rest of the evening. Has anyone ever seen their chickens do that? Is it totaly natural? I thought maybe they saw or heared something....maybe a cat, etc. Im not really worried but i am curious.
