Hi! I have 3 cream legbar pullets....and 3 roosters. I would like to breed my CL and keep them in a separate pen from my other chickens...my question is - how do I know which of my 3 roos to keep? I know very well I cannot have 3 hens and 3 roosters...that would just not work. So, I am planning on just one rooster. Tips for keeping the best one?
