I am newbie when it comes to raise chickens. An unusual eating behavior of my naked neck hen (age >1 year) was observed today. Upon inspection, I have found her tumid mouth and it feels like some malignant disease. In order to give an insight into this matter, here is the photo I have taken a few minutes ago.
I do not want to lose it (especially after my beloved production red died a week ago after thick mucus dribbled down her peak heavily). Please suggest some remedies to save her life if possible.
Your help will be appreciated.
Thanks for your time!
