First off, alittle background. Last week I noticed my chickens being stirred by something in the middle of the day but can't find anything wrong, other than a couple of times they have been upset and out of their yard. I would just go herd them back into thier yard and shortly they would settle. Oh yeah and my rooster has been sleeping on the ground. I have lost sleep figuring I had a predator harrassing them, and going out to check them everytime time the dogs start barking. Today they were squalking and raising commotion, I went as fast as I could get across the property only to find a stupid tree rat scuttling up the tree. Anybody else every have something similiar? Any suggestions?
