My flatmate (FM) has had 4 ducks and a drake for a couple of years now. This year he allowed one of the ducks to keep her eggs (14!) and we were very excited at the prospects of having so many ducklings. Three of the ducklings hatched and then Mum abandoned the nest. FM wanted them to be friendly, so took a couple of the ducklings to rear inside. One of them stayed with Mum. After one week, he decided maybe they would be better outside again. The other ducks didn't like this and were violent to the little ones, even the mother. One of them disappeared, so I did some research to find out whether things were going ok, because I didn't think so. After reading all of the posts here about rearing ducklings and how they can't be alone with adults (these adults DEFINITELY didn't like them), I brought her (now Bertie) back inside. They question is what to do now. She has a ducky soft toy (which she loves) and we take very good care of her (lots of baths, hot water bottles, attention, clean living space etc). However, my FM wants to try and re-integrate her again. The thought of having her out there with the adults is not a pleasant one for me. She's about two and a half weeks old. (That's her in my profile picture) tl:dr How old should ducklings be before they have (supervised/unsupervised) visits with hostile adults? Any tips you have on rearing single ducklings would be much appreciated. I want to do the best we can for her, since we've messed everything up so far. Thank you for your help.
