I have a 3 week old guinea keet who is the runt. Because he's been smaller than the other 2, I've kept a watch on him to make sure he's not picked on. Last week I noticed it was hopping around with it's new feathers ruffled. I caught it and inspected it. The joint (knee) looks a bit whiter than the other. The foot tried to grasp at things and the bird tried to stand on it. It continues to eat and drink and hop around. I've noticed lately though, it's foot is starting to turn out at the ankle. I've thought of taping the leg a bit or making a little brace so the bird can stand a bit better and not lose it's foot mobility. The other two are becoming very protective of him, keeping very close and protectively cuddling with him at night. Any suggestions?
