I just found my black silkie dead in the middle of the coop. I have 10 other chickens (now 9 hens and a rooster) and want to know what I should look for? She has no visible wounds at all. I still have her, and wondered if there is anything I should be looking for that I might have missed. I was out of town, and my neighbor (who is great taking care of my chickens) mentioned that she had been sitting in one place for a while yesterday. Last night she was sitting out in the run, so I checked her, and put her inside the coop. This morning she was eating and driniking, as she did yeterday even when she must have been lethargic. I went to pick up my car from the shop this afternoon and went out to the coop to find her dead.She is about 2 1/2 years old I think, could be almost 3 years. Thanks for the help.
