There has been a stray cat that has wondered here (38 acres probably dropped off). NONE of my chickens bother her. When I give them treats, she eats with them and everything is great. Is the reason Mr. Roo attacked my dog due do testosterone maybe? The cat is a female. Im so lost right now. My first set (5 hens) I've had for 3 years. The 4 months old I hatched on my own.
