I don't have photos, as most of them went to a friend of mine who wanted to finish rearing them by hand. But I've been to visit them, and they turned out perfectly healthy and happy .
Not a single problem with the 2 hens in the same box. We've moved the aviaries around now and they're in a much bigger one with lots more budgies, so I'm not sure if they'll nest in the same box again, probably not.
