Bump.
I had one Silver Lakenvelder die yesterday. This one was at the bottom of the pecking order for some odd reason. She was pecked quite a bit in the neck. So much that when the weather really got cold, all she wanted to do was try to tuck her head in her chest and puff up to stay warm. She refused water and food. Since she was being an "outcast" the others sometimes took advantage and pecked her until she was all alone for about a week. I tried to give her water multiple times with a syringe. But, she didn't want it at all. She had no symptoms of disease (at least what I could observe by behavior and externally on her). Since she wasn't eating or drinking, she was weak. I'd hold her to warm her up and she didn't care that I was holding her (when she was normal she hated to be held). When I'd set her down, she'd loose balance and nearly fall forward on her face. But, she'd correct herself and sit there puffed up blinking slowly.
I have one more Silver Lakenvelder and she is puffing up and standing quite a bit, but when I go close to her she runs (like normal). She eats and drinks like normal too. I'm hoping the other bigger birds don't pick on her... We'll see.
