I am frightened about what I’m seeing in my flock. Yesterday, I saw that one of the chickens had a wound on her front chest. I couldn’t catch her (they free range) and she didn’t come back to the coop last night. Today her wound is larger and bloody. My daughter was able to get closer to her and said there were maggots in the wound. Now, until yesterday, she was fine. She is an arucana and has lovely beige & brown feathers and seemed perfectly healthy. How could maggots grow on/in the wound that fast? Doesn’t it take many days for maggots to appear? She won’t let us near her. She is still running around and seems to be scratching and eating. But, her front is all opened & raw. I’ve been wondering if a predator of some sort got a hold of her. But, just now, my daughter came inside and said that another chicken, a barred rock, has an open wound across her neck now. So now I'm wondering if this could be some strange disease or parasite that eats chickens from the inside out. It seems to be affecting more than just the one chicken. My son says that the chickens are eating walnuts that have fallen from a nearby tree and the walnuts have worms in them. Could these worms be affecting the chickens? I'm worried about the rest of the flock. But I'm also worried that this could be something that will pass to other animals or people. I don’t know what’s going on. Do these symptoms sound familiar to anyone? Please help!
