Lock up ND kids at night in New Hampshire?

[L3thatsme]

I just brought home 2 Nigerian Dwarf wethers that are 10 weeks old. I have a decent fenced area (2x4 horse fencing, 4 ft) & a calf hutch for them. I locked them in the calf hutch last night & tonight, but how long should I do that for? After dark tonight, they automatically settled into the hutch (They're genius goats).

Obviously, I'm a newb. Any help would be appreciated!

Are you concerned about predators getting into your paddock? If so you can continue to lock them up at night. If you don't have a possible predator issue than there's really no reason I can see that they'd need to be locked in the calf hutch at night in decent weather.
