Ok, I am new to this. I was outside giving the chicks fresh water...and they all froze. didn't move...didn't peep...didn't blink. Stood like statues for 5 minutes. I know they either heard something, or saw something..but I don't know what. I stood out there with them till they made their "all clear". I didn't see anything, or hear anything. Anybody have ideas ? Oh, the chicks are all about 4 months old.....pullets and cockeral.
