Well, I'm home from work and Dixie is not only still with us, but seems to have perked up quite a bit since yesterday. She's eating warm oatmeal and drinking water next to me as I type this. It's one of our warmest days here so far (45 or so) and when I got out there, she couldn't wait to get out of the coop! She even seemed to snuggle a bit when I picked her up, like she was glad to see me. This one is a fighter that is for sure. I've checked for lice and bugs and I just don't see any on her. I think what happened, from the behavior the last couple of days is that Donald our drake Rouen has been trying to mate with her and in doing so got the feathers on her neck. We fixed up the divider between them so she can't fly over to the duck side any more and he can't wiggle through to her.
I'd still like to know what happened to our other girls and am hoping we are now in the safe zone with Dixie. I asked Jason more about it last night (I've been afraid to ask for details, as we both get teary when we talk about them and he didn't want me to see them like that). He said it looked like something internal happened and their vents were damaged from the inside in a pushing out motion and covered in blood. I'm starting to have hope that whatever was wrong with Blanche, Rose, and Annie (RIP my sweet girls) has not affected Dixie.
