I milked my new Nigerian Doe, and was reaching down to get the lid to the container that I milk into (not for drinking, it'll be for freezing) and when I turned around to put the lid on the container, she was drinking her own milk! Just slurping it down. Probably only got 1/4 cup, but when she's giving me only 1.5 cups a day (milking once a day, thin, and got her a week ago) it's kinda annoying, not to mention WEIRD! Should I be worried that she is drinking her own milk? Does she need a supplement? Also wondering if she'll start nursing herself..
