When I let my chickens out this morning I found my little white silkie laying on her side almost dead. She died a little while later. There was an egg right beside her. She seemed to have a bunch of poop on her butt. Her feathers were looking ragged the last few days, so I thought she might be molting. So sad to lose her. We only had her for about three weeks. Any ideas what might have happened? Also, are my other three chickens in danger?
