Our lamancha milks about 1/2 gallon a day, faithfully. Sometimes a bit more, but not much. Well the other day she found some weeds on the other side of the fence that she liked. So I pulled a BUNCH of them and put them over the fence for them to eat. She went nuts on them, happily munching. The next day she was at less than a PINT of milk. I was flabbergasted. Told hubby we needed to figure out what happened. The next day she was back up to her regular amount. And has been ever since. This was about a week ago. Any thoughts, is it possible that whatever that weed was shut down her milk supply for a while? I'm sorry I can't tell you what kind of weed it is, had teeny tiny little white flowers on it though.
