Hello, I have a hen that has been breathing strange for a while now. she is an older gal with a large tumor hanging off her chest. she has had that quite a while too. I am really suprised at her strenth. She wanders around acting as if nothing is wrong, exept...she stands there with her beak up and open almost gasping. I have also noticed she doesn't talk anymore, and when she tries to its quite garbled. Now I have been expecting her to give up the ghost a long time but she is a timex and keeps on ticking. This morning I noticed one of the other hens doing the open beak breathing thing just a couple of times. anyone familiar with this? Thank you in advance.
