What a sad and perplexing start to my morning. I went out to let all the chickens out and noticed my 12-week-old ancona, Dot, just sitting in the very back corner while everyone else is out pecking, drinking, etc. I went in and picked her up looking for any signs of injury, etc. put her back down and she staggered back to the corner again. I picked her back up to take her inside to isolate and observe her better and by the time I got in the back door she had a slight convulsion and died right in my arms. Last night when I checked on them before going to bed she was up on the roost with her friends just as normal as anything. So this happened literally overnight. There's no signs of trauma, she had been behaving like a normal pullet. Does anyone have any ideas? I hope it's not some disease that's going to wipe out the others. Thanks for any help you can give me.
