I just got my first two calves (ever) on June 1st. They are doing great and I am learning so much as a new (hobby) cattle farmer. My question is in regards to the grass in the lot they are in. I see that they are eating the grass well. But they leave certain parts of it alone. And it's growing taller and taller than the other parts. Should I periodically bush hog the lot? Should I get rid of certain weeds? Should I overseed? Thank you for any insight.
