I've been worrying about this now. I haven't had a way to get out yet. But in gazing long at the babies' eyes this morning, I see that they are turning brown. It's the same kind of color as a human black baby sometimes has, born with smoky blue - that blue that means they'll be changing. There is no sign of any infection that is visible. We only have four sheep, and in the whole year, there's been no sign of illness in any way. Where would an infection come from? Well, I'm going to watch them for the next few days, with all these things in mind, just in case.
