My husband kept 25 hd of cows that bred late. I have had 3 calves so far and they are all MEAN. 2 of them actually tried to charge me at 2-3 days of age. The other one was quite a screamer when I grabbed him to tag his ear. They are from the same bull as the earlier ones, but I never had one of those little 70 pounders try to take me 'till now. Is it something to do with being fall calvers? Or what?
