I don't know what happened. I came home tonight and found my Americana (Bwownie) sitting just inside the coop door. She had her mouth slightly open as if to pant and was just sitting there. I picked her up and didn't get much reaction. A little puff of neck feathers, no vocals, and that was it. Stumped, I went and got my kids to bed and came back out to check on her and she was dead. I looked her over, but couldn't find anything. She was out this morning with the others for their treats. I didn't notice anything off. The only thing different about her was that she has had a bare back for the couple of months prior. I thought it was either from our rooster or plucking. I was keeping an eye out for her, never any blood, just bare. What could have happened??? Should I be checking the rest for anything?
