hi guys, This afternoon I was bringing my chickens into the coop and noticed that one of my bantam partridge wyandottes had some sort of a mouth sore, She had a swolen type thing and I am not sure what it is. It is on the side of her beak kind of like she has something in the side of a pouch, but she had a swollen beak, I dont want this to spread to my other chickens, or cause her pain, so I would just like to know what it is and or what I can do to treat it! Thanks!
