One of our does loves rubbing her neck on the side of the stall. Well she got a splinter and it was sticking out so it was easy to pull. But there must be a piece left in there because it keeps festering. We have sqeezed it out several times but haven't found any more wood. It's also right at the top of her wattle so it isn't the easiest place to squeeze. I'm thinking that because it left a decent size scratch that it may just have gotten dirty and infected. I have LA-200 but have never had to use it. I think it may help to give her a shot to help with the infection. How do I do this? Where on her do I give it? How much should I give? And how long? Thank you for any advice or suggestions you may have.
