I think they had verus 5/6 boys but no girls would were hoping to do a swap/get some girls in to form a breeding group. not sure if that is still the plan though
Without them putting out any detailed information about the Chimps, current moves and future intentions, its difficult to ascertain what exactly is going on. However I presume in the first instance this could either mean setting up one verus group in the future, with the others kept seperate in other groups, or keeping them pretty much as they are but restricting breeding to the verus. (if they can add e.g. a couple of pure females to a group containing pure males)
Then if the new big complex ever becomes reality, they could still put all/the majority(?) of their Chimps together, but only breeding from the verus, along the lines of the Edinburgh 'Budongo' group. Gradually the others will die off leaving them a pure group.
P.S. this is a hypothetical scenario without any better information available.
