I checked on all of them this morning and the little ewe lamb looked a little wan, so I reached out to gently poke her to stand up as I had yesterday and she jumped up, ran for her dam and immediately nursed.
If they can run from you, things are probably fine. And they both already figured out how to do that. The new mother hasn’t cleared up all her placenta, but that is not so uncommon. It’s just lying around, and the black and tan ewe herself doesn’t look bad and was eating with typical vigor when I showed up.
These lambs are still less than 24 hours old, but it looks good from here.
