Three cheers for Chuck and Buck !!!
I assume they are well behaved boys: They would never eat the ferns from the window sills, won't watch nasty stuff on Pay-TV and they won't topple over the fridge and raid its contents?
- So yes i would cave in and let them in early. It is just for a couple of months and the worst thing would be a »sausage with gravy« on the floor.That's the reason why i wasn't using a heat-lamp for the ducklings this year. My Runners, who grew up under 24x7 light still panik when the light's go out. It takes ~30 seconds before the generator kicks in during an outage, but that's enough to send them over the edge.

This is a long-used method for puppies... it works brilliantly for them, so it should work for ducks too right?
