I have a 3 yo doe, this is her 2nd freshening, she was due yesterday but still no sign of labor other than her ligs getting softer. Tonight I just noticed she has loose stool. We wormed the whole herd a week ago and gave them their follow up yesterday (mollys natural wormer) we haven't changed feed etc. How do I combat this? I gave her probiotic, anything else? Is this pregnancy related or something else?
