My lovely Sicilia Buttercup has black around her nostrils and the base of her beak! Half the beak is affected, and I'm worried sick. I only have three chickens, and I've brought them inside tonight, and put neosporin on their beaks? Am I an idiot for doing this? I can't find anything at all about frostbitten beaks - just wattles, combs and toes. But I"m terrified she will lose her beak. I understand the blackened areas signify necrotic tissue. How will she survive without a beak? I realize I sound hysterical at this point - but I would appreciate any advice or experience anyone can give me. Thank you!
