i've a trio of ko shamo, two young cuckoo's male /female and a white hen, i was given a black ko shamo hen a couple of days ago and would be handy if i could keep them all together but the young male and the black start to fight if put in together, drawing blood, so i've been putting the black beside the others in a cage in the hope they get used to each other, after a day or so tried again with the same result. is it usual for a male and female to fight ? do some just not mix? do they just need to sort it out ? advice welcomed, thanks.
