My first time doing this. We got 40 heifers in Saturday avg. around 800-850 lbs. they were AI'D May 15 and then with 3 bulls until June 9. They're now with our bull. Anyway, our grass is doing great with all the rain and no cattle on it for almost 7 weeks. Clover, Bermuda, Fescue and others. We have 4 pastures all around 12-17 cres each. I only have the ability to split those 4 and make 8. The 40 heifers/bull have been on the first one since Saturday and there's still a lot of grass left to eat. How often should I move them? What am I looking for in the grass that's been grazed to signal rotating them? I also was thinking I should drag each paddock after moving them.
