I like @mashmaster borrowing suggestion. Start with your scout's personal safety - gloves, glasses, mask, headlamp.. in kit.
Don't worry if you don't have "this" or "that", a WFA class will teach what "this" and "that" you should carry and if you don't, how to improvise from what you do have. For example, using a belt as a tourniquet. Definitely pay attention to other bleed stop (e.g QuikClot, Woundstop) tools.
I have bought supplies from Chinook who have been helpful.
Consider the yurt a cabin not a tent. Whole troops with a full range of ages share cabins all the time. For the adults, do whatever separation makes everybody most comfortable, be it hanging tarps or the lone male sleeping in his truck.
Does a scout have any say? Only so far as the troop follows his suggestion. But there's no reason in this story to think the scout on his own took some of the proceeds of his sales and gave or ordered the giving of those funds to anyone else.
This is a news story that has two facts: 1) a scout sold $15k popcorn, 2) some portion of the money raised from those sales was used to help a local nursing home. There is a causative relation between the two facts: in order for there to be money to give to the nursing home there had to be a sale of popcorn. There's nothing inaccurate about the story as told, but in a local feel good news item of less than two minutes duration there's no time and no reason to walk through the obvious chain of events: 1) Scout sold $15k popcorn, 2) after paying council troop retainss $5k from those sales, 3) troop decides by whatever process they used (presumably including some input from scout and his family) to pass some of that largess on to nursing home.
As a practical matter there's no other way for this to work. Unless the scout only accepted cash, or cash plus checks made out to him personally, the money from the sales all has to pass through the troop's accounts, and ultimately it's the troop writing whatever check or other form the donation took.
It's just a pleasant little story to fill up one third of the time between two commercials on the local news broadcast and nothing more. Don't over think it.
I've seen an abusive situation happen in a large tent full of same-age (11 year old) Scouts, but then again, we were able to quickly put a stop to it and the offender was immediately sent home from the event and then barred from Scouting. That might have been more challenging in a 2-person tent where it was one kid's word against the other's.
I feel quite comfortable with our girls sharing a yurt. I just wanted an outside pair of eyes on the G2SS rules to make sure I wasn't conveniently interpreting it to suit my unit's situation.
Stringing a hammock outside (without rain and wind protection) would not be an option for a February campout on the Oregon coast, but it's definitely something to keep in mind for other outings.
A chill weekend taking my church youth camping, a much needed change of pace. All of my Jambo neckers were around some boy's neck for most of the day. They never got the memo that American scouts would melt if they wore them!
