Please help, one of my six backyard hens suddenly is acting very sick with what appears to be puss covering her right eye and maybe not able to see out of the left either. Also she appears to be bleeding out of her left ear. Could this be an infection? Tumor? I hadn't noticed anything out of the ordinary the last few days until I couldn't find her and found her crouched on an egg against the fence. I've posted pictures below to help. Thank you in advance!
