Just ducklings.
The mallard ducklings are probably not pure mallard ducklings. The female mallard probably mated with a pekin duck, which are the big white ducks, Pekins are yellow as ducklings.
You call the baby whatever its parents named it.
Baby ox
It's nearly guaranteed that they will kill the ducks, especially baby ones. They are different animals completely. My hen hatched her own chick and the others killed it two days later... If they will kill their own, they will kill ducks, too.
if the babies are about two to three weeks of age and their eyes have NOT opened then you should call a vet NOT a pet store sorry but they can give false advice
A lion is a male, Lioness is a female and a cub is a baby of the two.
you should call him in two days
it is very very uncommon... a bit like yer ma!
Absolutely not.

2/3 chance they get a boy, 1/3 chance they get a girl.
If you are a guy (and straight), then your motives are good and you should. If you two used to be an item, then you should not. You both have moved on and he has obligations that you should not distract him from. Every minute he would spend with you is not with his baby or the mother of that baby. If you still have feelings for him, that is natural and not something to feel guilty about but it is actions you are responsible for. Calling him would be selfish and not good for at least three other people.
