We had seven roos and the two with the least desirable personalities went into the freezer. Of the five left, I've had no trouble until today. My three-year-old grandaughter went in the barn to visit a new calf, and one of the roos took a jump at the back of her snowsuit. My son said it has happened before. She nearly always had on pink or red, and her snowsuit is red. We were wondering if the color set him off, thinking that is why roos have the prominent red combs--as a sign of dominance or something like that. Any thoughts?
