Apparently shearing Cookie-goat was the only thing needed to fix the horrible road rash and ooze on his chest. It's all dried up and gone now. The vet was amused at me.
He also recommended that I take Summer-goat's duct tape off this weekend. Unless she starts bleeding again, that's all for dealing with her broken horn. We may have to trim back some more splinters as the blood vessel retreats, but that will be on an as-needed basis.
