She has just given birth to twins. Now she is eating the afterbirth. And keeping a watchful eye on both lambs as she does so.
S has been watching the birth, and the second lamb, at her feet, is very small.
As a consequence they are now in the shelter mothering up. Hopefully the tiny lamb have a belly full of mother's milk when checked again before dark.
I havered about blipping this, worrying that its rawness might offend. I hope it doesn't. It is nature's way.
