Well, apparently my isolation chamber idea was not good enough, because the other peeps got into it and about pecked my little lakenvelder to death. He's missing skin all over his head and neck, but he was still alive. I pulled him out and as I don't have a third heat lamp, I pulled the underpad heater from my peachicks and set up a tiny box for him. Slathered him in neosporin, fixed him a liquid meal of egg yolk, yogurt, and electrolytes and now he's sleeping soundly beside my peachick brooder. Thankfully the wounds seem just skin deep and if I can keep him eating, he should be just fine... it looks a lot worse than it is, really. I called in to work and my boss told me to stay and take care of him.
The funny part is that my mom was -totally- freaked out and we got to have a conversation about how it was not the fault of the other chicks, that they were just chickens and they can't premeditate things like this nor comprehend what they did. She was so mad at them! I told her if she had to be mad at anyone, she can be mad at me for not securing the chick properly. I think she was also a little freaked out, because it does look pretty bad, but the second layer of skin is intact so its not like the chick is going to bleed out or lose organs or something really terrible. It probably hurts like hell, but the injury isn't going to get any worse from here... so I figure it can only get better.
