Robin,
Good idea, if he'll bring them over & transfer the frames, all the easier.
You mean not 'outside feeder' but an entrance feeder? Basically you stick it into the opening and a mason jar sits upside down on it? BTW, careful poking holes. You want really small holes. Really small otherwise it leaks everywhere. You can also look into a quail feeder. Uses same mason jar but has a trough around it... put a piece of rope in the trough so the bees don't drown. Works great, and only a couple bucks at TSC. BTW, putting either of these inside the hive, don't leave them too many days. Otherwise the bees might start building comb from your inner cover (talk to your mentor, he'll give you other options or timing thoughts).
BTW, Tractor Supply (TSC) has a horrible beekeeping supply area. You just don't know enough yet to realize it! I'd recommend avoiding them for now, not sure their quality is more than a one-time-use product. I like Mann Lake, but there are other good sources.
What's wrong with bees loose inside the vehicle? I do it all the time, I just wear my bee suit when driving... (sounds funny but it is actually true).
