I've heard that the call duck and the pekin duck are the friendliest.
They start breathing.
As far as I know, and seen... no.
If the result you want is a mallard, yes. If mallards can just breed with other ducks, yes, a mallard duck can breed other breed ducks.
No.
No, Ducks come in a variety of colors and patterns depending on the breed and species.
That is a matter of opinion. I have hatched runners and am considering hatching mallards. Decide for yourself using Google images or another search engine.
It is where two ducks of the same species breed and produce hybrid offspring. Commonly in ducks, hybrids are most likely fertile.
You can't just tell, you have to sex your ducks. The best thing you can do is take your ducks to an avian vet to have them sexed or just wait until they are old enough to breed which is about six months old, and see if the eggs hatch.
I Breed Ducks, And it Reall Depends what Tpye of Duck you Got, Like I'v Got a Muscovy Duck and they Breed In Any Season But i Dont Know about Other Ducks but i Think Normally Ducks will Lay eggs in the Spring.
albino, i think. how big are these ducks? are you sure you're not getting them confused with GEESE?
That's a certain breed characteristic.
When a duck is ready to breed, I find it will get "flirty" around other ducks. They stay very close and bob their heads in a slow or very fast way, and nuzzle the other ducks with their beaks. If you have male and female ducks, you don't really have to know, they will know themselves and breed when they are ready.
