ASSERTION: For Cub Scouts, I think the idea of six to eight member den is wrong. It's inherited from Boy Scouts and though it's okay, it's less than optimal.
PROBLEMS
1. Not every scout/parent is 100% committed. It's common to have 25% or more of a den missing a meeting. With 6/8 member dens, it makes the den look like 3/6 member den. I know the solution is program program program, but the issue is parents, parents, parents and conflicts, conflicts, conflicts.
Plus, den leaders are doing their best as volunteers. It's hard for them to put on a high quality program month after month, year after year. So, I don't believe program is 100% the answer to membership issues.
2. Life interrupts not only scouts and parents but also den leaders. When this happens in a 6/8 member den, there are few resources (i.e. parents) to pick things up. Often dens become inactive for months at a time and scouts leave. The cub scout ends up looking choppy and not that good.
As kids drop out or have boring experiences, they bad mouth cub scouts to their classmates. "Yeah, I was in it. We didn't do that much." "It wasn't fun." Peer pressure develops that knocks other cub scouts out of the program.
SOLUTION
Keep kids together in a mega-den by rank (grade). It makes absences less apparent because you always have a critical mass of scouts. It almost creates a positive peer-pressure to attend. "Hey, 20 of my friends are meeting tonight. I want to be there."
Our pack has started doing this with some success. The den leader focuses on program. The assistant den leaders get assigned six to eight scouts with the goal that every scout has someone that knows their names, offers them a smile and a greeting and can have at least a short conversation with them.
The big benefit is with the volunteers. More help because volunteers see they won't be doing everything. Also, when one volunteer becomes busy, there are three or four to keep the den going. It seems to create stronger fellowship between the adults too.
Also, you have more resources and higher odds that a parent will be a police man, fireman, military, news man, civic resource, teacher, sports coach, .... So the leaders have more resources to tap to deliver a high quality program.
HISTORY #1
My oldest son's cub scout den lost it's den leader when her son dropped before Webelos. I picked it up. We had four boys. I asked the other den leader of five Webelos if we should merge dens. She said no because she had her plans. Fine. We ran ours and things revived and picked up two new scouts. We had a great Webelos experience. In the end, the other Webelos den almost folded and the other den leader's son crossed into a troop with us. Go figure.
HISTORY #2
Our current pack's fell into doing this because a den kept adding members and it by default became a mega-den. We debated splitting them up, but how do you split up the friendships. So, they found a way to make it work. In Tigers, they started with 10 to 12. Right now, the Webelos 1 den is up to 22 scouts. Our wolf den is at 19. Our new Tiger den is at 19 ... lots of siblings. As with all dens, some scouts are very active. Others not as much. But the active scouts provide enough energy to keep the somewhat active scouts going.
CHALLENGE
The challenge we see is the meeting space and budget. Mega dens eliminate using homes. We have to use churches, civic/business buildings, library conference rooms or school spaces. Also, where den leaders often swallow cost for six to eight cubs, they can't do it for 20 cubs.
It's working and we like it. Our pack has eighty scouts with one Webelos 2 den, one Webelos 1 den, one bear den, one wolf den, one tiger den and one lion den. For one grade, we have over 50% of the boys in cub scouts. Go figure.
