My baby girl all of a sudden has developed this weird mark on her beak it's like acid has been put on her beak, it's gone soft, ripples and bloody colour it looks nasty, this developed over night, from all research ave done it appears to be beak rot. Am gonna take her vet tomoorw, also the other one seems to have a flaking beak and the other one has a darkened stain, I'm worrie that they all have it? What is the. Purse of it, if treated will they be ok???
