I have a charolais-Angus cross that has begun to bag up heavily. I have her down for April calving. Today I notice while riding pasture looking for newborns, my bull and this cow were walking a back fence away from the herd. I kept watching them as I rode around and the bull is walking this cow all over the place. This evening when I went to check water here they came by the coral fence, her in front and him behind. He hasn't tried to mount her, just walking. Is this normal and he thinks she is cycling? I have never seen this with a pg cow and bull. The other cows pay it no attention.
