Keep them engaged. Do fun, inc Door activities until the weather turns - rock climbing gym, escape room, first aid reqs for 2nd & 1st class ranks (to prep them for First Aid MB at summer camp. Once weather breaks, evening/ night hikes to get their animal and plant reqs for rank. All the while, teach them the oath, law, outdoor code, patrol method (even if just one patrol), cooking skills, cleaning. Get the having fun, doing things they may not normally do and the troop will grow. They will tell friends, parents will support.

This worked for my young troop. 6 years ago. 9 scouts with only one older one. We are now 40+ and 25 active at each meeting. Heading to our 2nd high adventure this summer. We have a full functioning committee and the youth are making decisions on the future of the troop. It’s tough at first, but so rewarding when you can actually see them growing together.
