I have a Lamancha/Nigerian doe that is between 4-5 years old. She is currently 3 months pregnant with her 4th set of babies, but is not producing any milk. I have not taken milk from her in a week but her udder is still empty. I have witnessed her last 3 pregnancies and she has never done this before. She is physically healthy and has been acting completely normal. I am not sure if I need to retire her after this or if there is a way to make her body produce again. If you guys have any ideas can you please help me out.
