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?

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.
