In one group of about 10 chicks, I am noticing beak damage. Right at their noses a chunk of beak is missing. They are about 3 to 5 weeks old. At first I just thought someone had pecked it, but when I moved them to new quarters. I noticed more had problems with beaks, and one or two the beaks were snubbed. They are healthy, eating and drinking. I raise about 70 babies every month or two and never came across this before. There is one older bird about a month and a half in there with them. But I have never seen any pecking from her. I moved her out today, just in case. What can I do. I tried to search on the internet but haven't found any info. Help! Only 1 Serama is infected, the rest are old english and cochin.
