My orpingtons over the last few days have started following my dogs around. Yesterday they are what I think of as attacking. I have 2 as well as a cuckoo maran. She has followed suit. My dogs are small and have never gone after the chickens (2 dogs weigh less than 10 lbs together) now they can hardly use the restroom outside. The chickens free roam our fenced backyard in the city. My maran laid her first egg today, could this just be all the gals ready to lay and that's why? If not how can I stop this?
