Having a gander of approximately 4-5 months old. It had a toenail broken earlier this week and had blood lost. The blood stopped eventually, but as it sometimes raises its foot with the broken nail, I think it hurts to him. Today, the gander could walk earlier, but since a few hours ago, its behavior has been unusual. It was standing, without ever sitting, near the water/feed area, drinking water but not eating the feed, for several hours. Giving it oats, which are his favorite, didn't lead him to eat - lettuce and watermelon, either. Then it didn't stand but instead cannot stand, his legs weak. I put some Sav-A-Chick water, but he hasn't drunken any. We also noticed its butt not clean, which is unusual, too. When it was still able to stand, it kept shaking its butt/tail. Is there any emergency thing I can do to prevent him from dying? Update: It looks even weaker now. Laying on the floor, with wings drooping. Still hasn't drunk anything.
