The neighbors goat, which I adopted looked like she had a slightly swolen area above the right (starboard) teat. I checked it and it felt slightly warm, but no warmer than the rest of her, so I pulled on the teat and a sticky clear substance came out. She didn't like that much, so ran, but I recornered her and tried both teats and got milk out of both. It was very oily, sort of a buff color, had no smell, tasted like mare's milk, but was still very sticky feeling.
There are no other goats around her and she has been in their back yard for over a year, so could not have been bred.
Is it possible or normal for a goat to have milk and not be pregnant? She was just in heat two months ago and has been at my place ever since. Am very curious about it.
