I have a 1 1/2 year old Ancona hen. She has developed this strange growth on her beak. The mass is firm and 1/2 is solid and 1/2 is bristled like a brush. She also has black scabs? on her comb and appears dehydrated. She is separated from the flock now after being harassed by the other girls. Yesterday she drank a lot of water and ate a large amount of food. Today she is weak, lethargic, pale and one eye is a different color than the other. Blindness? I am sure this is terminal at this point, but would like to know what this is! Any advice would be appreciated. Google has let me down as I can find nothing about it. Thank you!
