Goblin is still having a serious case of the miseries. He stood up for breakfast, but didn't come outside. I took his dish to him and held it while he ate about 2/3 of the grain. I brought him water and supervised a big slurp. He then went back into his corner and slowly sank back into his misery-curl on the floor. I brought him a big flake of hay, and when last I saw him, he was methodically munching his way through it at glacial speed.
The vet said that either or both of these guys could run a slightly elevated temperature today, so there isn't much for me to do besides run through the elementary school checklist. Since all digestive systems are functional (rumination=warm) I'm just going to keep watching Goblin and leave him generally alone until/unless something shows up.
ETA: Goblin did come out to meet Katie-goat's people when I was giving the tour. So he's at least feeling somewhat social now.
