Another thing, you mentioned a heart murmur and a goat the is low in selenium could very well have a heart murmur. It is also called white muscle disease and it will affect the heart. You can give her a Bo-Se injection and you should see improvement in 24 hours if that is the problem.
Also, I don't know where you live but liver fluke is another possibility.
