I noticed my bull breed one of my cows today. The only problem is she calved on Feb. 9. I would have expected her to be bred already. This is the only cow I have actually witnessed bred. Ive watched him follow cows around and attemt to ride cows. Ive not noticed any cows in heat or bullish cows. Of course im only out there a fraction of the time. I just figured that she should have been bred by now. Should I be worried about my bull?
