Ovaltine has gotten less coordinated in the past couple of days, and ended up trying to sleep on the floor early this morning. So we caught him up (Ovaltine was sadly easy, and only one Spice finch came out and [pretty] quickly flew back into the Finsterium) and took him to the vet. The trip itself was difficult, since it was only 9 degrees out. I put a towel and a heating pad in the bottom of a box, put the travel cage in, and then put another towel on top. It worked. Unfortunately, the vet wasn't really sure what was going on. Her best bet was liver and/or kidney problems, because of the overgrowing beak, and because of the weakness suggested by his coordination problems. So, he's in the hospital cage now, on the steroid prednisone. But it doesn't look like he'll make it.
