Okay so we got 3 Pekin Ducks (2 males, 1 female) from my dad's friend a few months ago. Until a few days ago, all three ducks were inseparable and sometimes the "Male 1" (head of pecking order) would bite the neck of the female. HOWEVER, Male 1 and the female have started to exclude the other male by chasing him away whenever he comes near and attacking him at the same time. Does anyone know what we could do to help? Thank you so much!!
