We have a doe that we noticed a small lump on the back of her udder a couple of days ago. We have been milking her twice a day and massaging the lump to see if it will go down. The lump has not changed, but tonight she is acting a bit lethargic and has very little appetite. Her temperature is 101.2. Should we be concerned about hypocalcemia and possibly mastitis at the same time? We did see specks of orange in her milk this last milking. She's not hot or swollen.
