This morning as I let my goats out to graze I noticed on of my does had a knot right under the skin. It is slightly larger than a tennis ball, and it is located on her right side (as you would look at her from behind) right over the rib cage but closer to the end of the ribs toward her back. It is very prominet, and it wasn't there last night. I touched it and it doesn't seem to hurt her at all, it was very hard. I saw no blood or bite marks (we live in Texas and have many snakes) She is eating and acting just as normal as ever. Could this be a type of bite, or maybe someone else butted her with their horns? If you need any more info , I will try to answer. Thanks in advance!
