I had a pair of mutes. For no reason I know the female died. She was about 9 months old and he is about a 1 1/2 years. Man only has year old males left......will they be ok together? I'm not interested in raising little ones. Have a large pond and they live outside 24/7. Have read that many in the wild are also same sex pairs. How would you introduce them if I can put them out together. Live in North Florida. Thanks
