Came home from work to put some feed out for my calves and noticed one of my heifers was slow to come up.. when she finally came up (about 1-2 min after the others) I noticed she had one ear droopy compared to the other.. she pushed right up to the bunk and ate.. I've always heard you can tell a lot about the health of a calf by there ears... she's a weaned calf will weigh around 400#'s.. I didn't notice this on her this morning when I checked them.. any advice would be appreciated as this is my first set of feeders
