Hi, thanks for your reply. We have the 5 females and one male, started off with just one of each then they hatched 4 ducklings, now its one of them that has hatched this new baby, she was sat on two eggs but only one hatched. Yes she comes out about 4 times a day about 20 mins each time, I won't leave the duckling in the garden when I go to work COs my cats will have it, they don't bother with the adults, but a fluffy duckling looks tasty to them! Plus I don't want to leave the male with the duckling yet. Umm I can't see any mites, they was moulting couple weeks ago COs they is feathers everywhere. When she comes out they have a wander around and go in the pond, soon as the duckling is big enough they will have the run of the garden like the adults.
