HI! This doe that kidded on wens. I think she has Mastitis. I noticed it tonight when feeding, her udder was hard and hot. She is nursing her kids, and when I took her to the stand and felt her udder better I saw the following: One side was hotter and harder than the other-- one side expressed milk easily and had plenty of it it seemed-- the other side was hard and the teat had no milk in it and I could barely get any milk out! It felt horrible!! I massaged it with bag balm. Should I treat her right away? If so should I use the product Today? OR should I test first? If so where do I get a tester?? The doe is more quite than usual tonight too. Please advise! I am really worried about her! Thanks!
