Well, so far (2 nights) they do seem to be going back in the coop.
Though last night they seemed to want to swim more than go inside. Not entirely sure what got them out of the pond so I could herd them in the coop.
I will say these things are the most skittish birds EVER.
And yet the most hilarious. They remind me of nothing more than the Finding Nemo "Mine Mine Mine" seagulls. They talk constantly and that's all they seem to say (though it sounds less assertive when the scovies and geese teach them what "mine" really means in this area)
