We're pretty new to this chicken thing. We've got two Japanese bantam roosters that have started fighting. They're about 8mths old. They've been fine all summer long and have only recently started fighting. One of them may lose an eye. It looked pretty bad this evening. We've got 18 hens. They free range all day. I'm just not sure what, if anything, to do about them fighting. They're such beautiful birds and it just kills me to think of the one that's injured. Any advice???
