I buried this in a series of exchanges with A Cool Secretary, but I thought it might be better as a separate entry.
The baby is now fine. He's got the right location for dinner, and can run, will follow the dam now. I drove up, and he was in the "nursing" position on her blind side. He walked under her belly, came out the other side feeling frisky and ran a bit. Then he wanted to lay down, but couldn't quite manage that one. Several attempts later, he gave up. It's just TOO FAR DOWN.
Coqet wanted to come to me, but he ran off the other way... he won, at first, but eventually, she brought him over, then took him down the lane to her favorite spot at the end of the trailer beside the fence. The herd was drinking, so as soon as someone saw the new baby, they charged, en mass. Coqet was too nervous yet for that exuberant a welcome, so she took him back into the pond pasture, and the herd lined the opposite fence, gazing raptly at him over the driveway. Seeing him now for the first time, no one would even know he had a close call this morning.
Now, he's got the getting up and down solved, and does so with great aplomb. He laid down too near the fence separating him from the herd, so Coqet was busy laying her ears back and keeping everyone at least 20' down the fence line from him. Finally, she got him up and moved him across the driveway from the fence, where he again lay down promptly.
I called the school secretary and told her I'd see her Monday -- then called the vet to do the check on Angelina, which is slated for Monday at 11:30... Things are getting a bit crowded. I'm definitely in Grandmother Mode.
