And Paula, you should see the beautiful fillies she's had. I'm very proud of this farm, as she is also raising PURE Falabellas, and has a few of mine there as well.
I think, Deb, once you see her in labor, I'd call the emergency number for the vet, and have her enroute. This really does appear to be a large foal -- all on one side -- but if there ARE twins, it might be difficult for the first one to line up.
Better to have a vet arrive to a new foal safely on the ground, than be too late to intervene if necessary. I know you're very experienced, and have saved many a foal, but better to be safe, and have her arrive in time to either greet the new little one, or put her gloves on!!!
You need to post pictures of those precious six little filles for us to see! They are just beautiful!~
