I have three goats that are pregnant. I am concerned about one. I ve been waiting on babies for a month. This will be the goat's second time around and my first as a goat owner. I have watched for all the signs and we are getting close. however, I am concerned that her vulva looks a little crusty like there has been some small amount of leakage and dried. Do you think she ll deliver soon? Should I clean the vulva area? I will try to upload a picture.
