for people who love the littlest dairy goats
I'm curious how you know she's coughing up mucus rather than her cud. It's not that uncommon for kids to cough when they're learning that whole process of bringing up cud to rechew. It even happens to adults once in awhile. If she is chewing before or after coughing, this is probably what it is.
As for stuff coming out of her nose, again I'm wondering if it's really mucus, or if that's just what you assume it is. Since you didn't have her as a kid, I'm wondering if she has a minor cleft palate. The reason I mention her being a kid is that she might have had milk coming out of her nose when she nursed, but depending upon the severity, might not have been too bad, and she learned to compensate for it. You can check her palate but running your finger straight back in her mouth towards her throat. Stay away from her molars. :)
Here is more on the many causes of respiratory conditions:
Whenever I call the U of I vet clinic, it's usually inevitable that they'll say at some point in the conversation that they can't diagnose over the phone, so I need to bring in the goat. It's even more tough trying to figure out what is happening when it is described in writing. Environmental conditions can cause coughing. It is more likely caused by bringing up cud if you see that she is chewing as soon as the coughing fit ends.
You're welcome! A vet professor told me many years ago that she had a hard time getting too excited about a goat if it was still eating, drinking, chewing its cud, and walking around. So, that's usually in the back of my mind when I see my goats acting weird or different. Sometimes different is bad, but sometimes it's just ... different.
