Two of the three disabled Spitzhaubens I hatched are getting around better, eating, and growing. The third is not doing so well. I took its booties and brace off this morning, and it just sat there. I fed it uncooked egg yolk (yell at me later about the salmonella risk), and much to my shock it's hobbling around on its own! I put it in the brooder with the other chicks, and its trying to eat crumble. This little chick has struggled so hard to live. When do I stop feeding it with a dropper, propping it up, and trying to help it? I seriously don't think it will survive and be normal, but I want to give it every chance. Please advise.
