I just got my first chicks on Friday, and they were doing great until I added 4 more today. I have a total of 9 chicks. Two of my new ones today are barred rocks, and they are picking on all my other chicks. My 2 Sussex and 2 americanas all got both eyes pecked and I had to doctor them, and my 3 buff orpingtons were being dragged by there necks and wings even though they are much bigger than the barred rocks. I seperated them for now, and as soon as I did the Barrera started fighting each other. Should I just get rid of them?
