I have an emergency with two of my 4 chickens, their beak seams to be corroding away, one of them has half of the top part of her beak missing and she can't eat!! Yikes, i don't know what to do, and have been unable to find anything like it on BYC message boards. I am in dire straits and a novice with chickens. I only noticed it today, because they always have stuff on their beaks so i don't pay much attention until i bent down to give them some water and socialize a bit. They seem active and fine but it looks really bad. Their combs are a bit floppy compared to the others. I have already isolated the two with the problem but i don't want them to die. They are about 6months old. Any advise/help is much appreciated. The second chicken (ie the second pic) she isn't too bad yet but she has the same black looking growth that is sorty of wanting to peel away much like a nail fungus, but i am no expert. Yes that is her beak missing, i didn't photoshop it> it looks really bad. You can image how/why she can't eat. This is what makes it so urgent.
