Greetings to all! I am fairly new to this chicken thing, but I did my research prior to getting started. I know of several predators in my area such as eagles, hawks, and raccoons. I have also seen a rat on the fence because of the wild bird seed. I do not put any type of feed in my chicken tractor to entice anyone and it closes completely for safety. The other night my dogs had a rat trapped under the dog house. 1 day later I came home to find what was left of said rat in the yard, a little fur and the bones of the hind leg. I have a Neopolitan Mastiff and a Yorkshire Terrier and while I am home 3 silly chickens running around the yard. The dogs and chickens get along, but I am always alert for change. My Yorkie is on the job and at 11 years old still a force to be reckoned with. Crazy thing he is! When he was younger he attacked a reccoon on our front porch. I know it could have been very ugly as he is only 4 pounds. I don't know who was more shocked, me or the raccoon! I am glad this rat is gone!
