I have two Indian Runner drakes, no females, they live with my chickens and are almost a year old. I got them together unsexed last spring hoping for two females but ended up with two males. Everyone has been living happily together until this week. Spring is in the air and I guess the boys are feeling frisky. They are generally well behaved when not near water, and they are good and don't harass the chickens, but when they are in or near water they immediately start biting and trying to drown each other. As soon as they come out of the water they are pals again. Is this something they will stop doing? Or now that it has begun will they continue to be aggressive towards each other? I'm trying to decide if I can keep them as pets who double as insect control or if they would be better off rehomed. Thanks!
