I've noticed now at least 3 times where I've seen my 8 mo. doeling that she starts to quiver sometimes. It doesn't seem to be a full-on shiver, but just tremble for 3 seconds, stop, tremble for 3 seconds, stop, etc. It's pretty cold out here - about 22 degrees right now, so I guess she could be shivering from cold, but none of the other goats are doing this. The only other thing I can think of is maybe low blood sugar? The last time I noticed it was when we took her on a light hike, and I noticed it this morning before her first feeding (they ate at 7 p.m. last night and then 8:30 this morning) Can goats have this kind of problem? If so, should I administer Nutri-Drench? Or will that just shoot blood sugar up and back down? Any long-term solutions?(less grain, more hay?) Any help is appreciated!
