I have a milk goat that produced very little milk when I got her. I am not sure the last time she had babies. I just noticed that her sack is so much bigger than I have ever seen. I have 2 sheep that stay with her but they are both cut so there is no way that they bread her. We do have a neighbor that has goats that could have jumped the fence. So I guess my question is would she start making more milk if she is not pregnant or should I start watching for babies?
