I have 6 four week old RIR's that I have just transferred from the closet to the coop. One of them (named Teriyaki) has started freaking out for no apparent reason. She will suddenly start cheeping VERY loudly and run from one end of the coop to the other, smacking into walls, eventually trying to crawl deeply into one of the corners. These freak-outs have lasted up to 20 seconds long. Any ideas what that is all about? For a little background info, while still in the closet, she survived a ninja attack from our cat while I was in there laying down more newspaper. It was a close call, but I was right there and able to break it up quickly, but not before a little blood was drawn. Have any of you seen this kind of behavior before? Is Teriyaki just a little "touched" in the head? PTSD perhaps?
