I know my dogs get extra frisky and will run and play more now that the weather is cooler, but my chickens act like they have lost their mind. I let them out every morning to free range and put them up at night. Sunday morning when I went to let them out one of my hens bit me on the foot hard enough to leave a mark for no reason. Then later on I noticed one of my hens kept trying to pick fights with the other hens. Last night my roo attacked my dog and scared the poor thing to death. Then, this morning my roo came flying at me in attack mode while I was walking back to the house. Since the weather has cooled some everytime I let him out he runs around like a lunatic, puffing up and making noises. What do you suppose is the cause of all of this? Could it be the weather? Or has he just gotten to a crazy age or what? Any advice or opinions are welcome.
