My 5 guineas are 5-6 months old I believe I have two girls and three boys. They recently started attacking my four ducks that are 7 month old females. For whatever reason they leave the drake alone. I am able to keep everyone seperate so it's not a big deal. But of course I would like them to live happily together as they did when they were little. Is there anything that you can do to stop the bullying/attacking? Also, any idea why it's the girls only? Why don't they pick on the drake? Thanks for your help!
