Let mine out for the first time this afternoon (after 7 days), for an hour before they usually go to bed. They were quite well behaved, if a little unsure, and I wanted to see what they would do about the ponds. I have netted them both but I watched them like a hawk, and so far ok.
When my nerves had frayed I shook the corn tub and they came to a light trail into their run and some handfuls to go into before bed. They did a bit of running and wing stretching, but I think I'll have to clip their wings just in case!
