I have 10 roosters, and 15 hens. A few weeks ago, one of my Japanese bantams had a bloody neck and comb when I closed the coop, that next morning she was dead. (rooster). This morning when I went to open the coop, another Japanese Bantam has a bloody neck!!! I could not get him, so I will have to tonight and put him on the porch- what should I do? I do have 3-4 aracuanas that are aggressive and do a little fighting dance, puffed up feahters, etc. One in particular, went at my boyfrineds ankle, my sister, but not me? Should I seperate the group somehow, if so, what ratio of hens/roosters?
