Boys will be boys.. $hit... girls can be even worse... trust me

I always used to keep all my dogs loose in one big paddock... For yrs I had no problems, they knew the pecking order and I was at the top of it if there was any confusions about the way things were...
Let's just say I don't leave home now till the dogs are all put up in seperate pens... when I'm home I'm not worried about anything... but when you're not there, things can get serious real quick...
Seperate them (securely) when you ain't home, I had to learn the hard way.
