So I live in Kenya, and I was given an adult hen when I purchased some 3-month-old chicks from a woman. I suspect the hen is older, but she says it still lays eggs. She gave the hen to my 5-year-old son who immediately bonded with her. The hen looked healthy when she was given to us. However, on our walk home she began gurgling and growling as if she was broody and didn't want to be touched. Then she let out a big sneeze/cough. By the time we got home, her comb was quite blue and she had coughed several more times. We were not prepared for an adult chicken, so the chicks went into the coop and Princess Chicken (as my son named her) slept outside in the fenced run. She refused to roost, but found a safe place in a bush. It poured rain all night, and in the morning I found this ball of soaking feathers, gurgling and coughing. One she dried off and warmed up, she was a normal happy chicken all day long! The next night, as soon as the sun started going down, her comb slowly started turning blue again, and eventually she started gurgling and coughing again. We put her in a large cardboard box under cover from the rain. She was dry, so in the morning, she was pink and chicken-y. I've done some research and learned about a parasite that rests in the windpipe blocking a chicken's airway. Could this be what Princess Chicken has? Though it only comes out at night, which I think is odd. Do you think she's contagious? Can I treat her with a deworming medication? Any advice is much appreciated, as I don't completely trust the advice of my Kenyan friends who believe in a "chicken vampire" who comes in the night to suck their blood! Thanks in advance!
