Going to get intouch with Slimbridge to see if they will take them, apparently they have a unit there for such purposes and they need more room and warmth than I can give them now. Not sure if they will be interested in some common Mallards but find out in the next day or two and hopefully they will grow up into wild ducks not domesticated ones. Failing that it will be gas mark 4 for 2hrs and a jar of orange sauce lol
