I have a mixed flock of Chickens, Bantams, Ducks, and Guineas. They all co-exist in relative harmony. But, recently my male Guinea (Ace) has become enamored with my Jersey Giant Rooster (Oscar). Ace has a Guinea Hen girlfriend (Jean) and recently she hatched out a small brood (which I was able to find and put in a brooder inside, they would not have survived otherwise). While she was sitting on her nest she would come to eat, drink and hangout everyday. During this period when Jean would be gone for longer and longer periods Ace developed a strange relationship with Oscar. Ace is now never far from Oscar's side, he runs circles around Oscar tries to run under him gets snippy at times when the Hen's get close to Oscar and just the other day I saw Ace crouch down and allow Oscar to mount him. Now, I honestly would not find this odd if it was two of the same sex, same species, but I am scratching my head a little at this duo. I thought I would just inquire if anyone else has experienced a similar situation and what if any problems arose?
