I had a jersey for a year and she did great and I raised a bull up and butchered him at 9 months. But I was wondering when you have a mature bull does he need to be seperated from the heifers when they are pregnant? I think no as Cows are not rabbits right. Also would I have to worry about my little kids being around a Dexter bull? I am assuming that Dexter bulls are a lot safer than other breeds from what I have read. I use to have a small chain I kept on Bessie like a collar so that I could tie her up to graze in the front yard Could you leave a halter on a cow all the time? I have never used one. My little pasture area is across the road so I would need to lead any cows back and forth everyday to and from the barn for milking I could use a chain like before but I was just wondering if a halter is better? If I was a cow I think I would rather have the little chain around my neck seems like it would be more comfortable. Here in Kosovo lots of folks I have seen tie a rope around the cows horns when they tie them up to graze though more often then not an old man or youngster just watches them when they graze as their is very little fencing here.
