Thank all of you for answering previous questions on here. 1.) I noticed yesterday a cow that appeared to be in heat. My bull was trying to get to her and another cow kept trying to keep him away. The cow trying to keep the bull away would mount the cow in heat and the cow in heat wouldn't move, then when the bull would try to mount the cow in heat, she would move away. What is going on here? 2.) I have an older cow that I would estimate to be about 13 years old that seems to keep coming into heat (last time was this past Sunday). I have seen my bull breed her twice for sure. Her last calf is about 11 months old and was weaned at 7 months. Would she be showing signs of being in heat and allowing the bull to mount her is she was already bred or is she just too old? Thanks in advance for any help.
