A friend sent me this pic of her BA doe ... with a lump in the udder. You can see it at the top here, its about the size of a tennis ball. The doe is milked out in this pic, its barely noticable when she's full. she's been tested neg for mastitis, neg for CAE. she's been given antibiotics and that hasnt helped. it doesnt seem to cause her any discomfort, and other than the lump she is normal and healthy your thoughts as to what it might be and how to treat?
