I gauge by their behavior, not their bags or springing. One of my 10-year-old cows calved a couple days ago and her front quarters weren't full, nothing "woah!!" from the back side view. But I know how she rolls and she doesn't fully come into milk until after she calves. But she did make a point of leaving the herd and bellowing from the fence close to the house, essentially demanding cubes. I'm a sucker, caved, walked out of the house to give her cubes - because I knew she would calve that night. Found her with a big, gorgeous heifer calf the next morning.
