Are all chapters not getting quota during formal rush or just the smallest one? Many years, including this one, we have a couple chapters not get quota (out of 6). My campus has also always seemed to be cyclical with chapters of fewer members years ago now among the largest and vice versa - is that happening here?
As an alum of a chapter who is 'smaller' I do take offense to the comments that those groups are somehow not good enough to be greek. Sure there may be problems but the largest groups have always had as many or more problems, just in different areas. And I agree that asking that group to double in that amount of time will be a tough task - I've done it, believe me I know
Luckily there is equity in housing with this situation so that isn't the issue - I would suggest if other sororities really want to help the situation to step forward and offer help directly to the chapter. Whether with joint workshops or helping them advertise their COR events, even the smallest bit of help will make their task a bit easier. They most certainly feel the pressure of their situation and would likely welcome the support from their greek sisters.
Good Luck and try not to let it divide Panhellenic
