Dog yard in the woods

I keep my dogs in very very large pens because of the type and size dogs they are. I can not keep MATURE dogs of same sex together in same pens ESPECIALLY females. Its a pain to even keep mature females in pens next to one another. They hunt together fine but can not allow them access to one another on the yard. My dogs aren't curs but no matter what dogs I have, I see same thing in mine. From BoarHounds, to Alaunt type, to stag type, I experience the same especially in the females. The males tend to vary more with their tolerance and friendship with one another. I won't leave mature males together for days at a time. My dogs are kept at my house also and not somewhere far away. My suggestion is multiple dogs of same sex in same pens is not good idea
