I have a Hen who is like coughing, Sneezing, Not sure what but keeps making a high squeeking sound. Sounds real odd to me, never heard it before. What is wrong with her?
1. First, separate her from your other chickens. Make sure she has food and water available, but is not "sharing the same air" with your other birds.
2. Use the BYC search box (up there on the right) and type in "coughing hen." You'll find lots of information and suggestions for a treatment for her. Good luck!
My hens will periodically do that also. I think that sometimes they eat a feather or who knows what. Mine will do it for awhile, then it goes away. If there is no other symptoms it may be just that. Keep a close eye out just in case.
