I am bottle feeding my first calf, and she is doing well. She is four weeks old now, and I would like for her to start eating some hay, but she is not interested. I built a little hay rack for her, and have hay in it 24x7, but she doesn't seem to want it, and has yet to touch it? Is there something I should be doing to get her to start to eat it? I feed her 2 quarts of MR twice a day, and a little bit of calf manna, which she just picks at (eats less then a pound a day). The calf is a Hereford. Is there anything I should be doing differently? Thanks.
