So I feel terrible, this pullet was 8 months old and not one that would let me touch her. I've been gauging my flock off of the birds I can handle. She was so thin the couldn't have been any meat on her breast, her keel was very pronounced. My other birds I can feel their keel but its not sticking out so much. I don't see any sign of worms in their feces. They were all eating, including the dead one. She did appear to have some nits on her, so I inspected the rest and found 1 heavily infested with nits and lice and another just with lice. I dusted them all. But does this sound like worms? I don't know how much of their keel should be able to be felt. I recently had one chicken found dead without a head in the run, but this last one showed no signs that anything was wrong prior to her death and showed no signs of predation. I use acv in water and fermented feed 1-2 times a day as well as dry feed offered. Any thoughts?
