One of our 3 1/2 year old does had huge healthy twin boys this year. We sold one as a buckling and one is still with her as a wether. when the first one left I was milking her out once a day to help her adjust to the lower need for milk production. She seemed to even out and had her boy with her to drink the rest. Now last week I noticed that one side of her udder is way smaller and yesterday I got her up on the stand to check her out- one side producing normally and the other side seems to be completely empty and has gone dry. I know the big kid has been drinking from the full side as I watch him do it! The udder seems to be fine and doesn't look or feel inflamed or swollen in any way. This is her 3rd batch of kids and we never had a problem with her udder before. Is there anything I should be worrying about? Also, we had a very bad plague of tiny biting flies this summer that were attracted to some of the does udders. Can they spread disease? We do have another goat with mastitis who has been completely separated for weeks and they don't come in contact. Should I have her milk tested at the vet? How would I test the dry side? No matter how long you have goats, it is always a learning adventure!
