I noticed this morning that my chocolate runner hen has a broken bill, and I have no idea why! It's not bloody, doesn't look traumatized at all except for the fact that half of the top part is missing. You can see her tongue! I've seen a duck like that before, but it was congenital--hers is definitely not. She is just about a year old and was born with a perfectly normal bill. It is possible it's been like that for as much as a week or two, because I don't examine them closely on a daily basis. Because her tongue is the same color as her bill, it is not obviously without close observation. I had to catch her to even be sure I was seeing right. She doesn't seem distressed by it--she's eating and drinking normally with the others--but it's very bizarre. How could a thing like that happen? And how could it happen without any obvious signs of trauma? It could have been developing slowly--perhaps some sort of wasting disease or parasite? Or is it more likely an injury? But how?? Does anyone have experience or know what might have caused it? I don't think there's much I can do about it, unless it's a disease or parasite I can treat, but I'd like to know what's up and whether she's likely to be pretty much fine in the long run anyway. She's a good girl and I'd hate to lose her. Thanks!
