If I knew which kind of duck you are speaking of I could better answer you question. As a waterfowl lover, I don't know of any ducks who's beak turns white naturally. I would call your vet ASAP.
Yes, and the offspring would be a a sterile F1 hybrid called a Mulard or Moulard.See the related Link listed below for more information:
White
It would depend on if you are speaking of wild species or domestic. There are crested ducks that have a tuft/fluff ball on their heads. They are called Crested Blue Swedish Ducks. In the wild this are no primarily blue ducks that have white tufted heads unless they are a cross between a domestic crested duck.
This would be the siberian husky, they are white, black and white, red and white, and sometimes grey.
if there was a female ducks or any kind of species would want to fight for the female. but if not there might have been something wrong with the now dead duck.
Yes, they can be bred together, but obviously, some traits from each breed would come out in the eggs (or the ducklings). This would create a crossbreed between the Pekin and the Cayuga, the same goes for any other two breeds of ducks bred together, e.g. Mallards and Muscovies, or Pekins and Muscovies. The Cayuga itself I believe is a crossbreed.
brown white black because some ducks live in trees. so if you were a bird and you had to protect them and you lived in a tree you would want to blend in. like wood ducks.
clayton
That would be the famous Holstein.
it will depend on the breed of duck. for example a Muscovy ducks name would be Cairina moschata and a Domestiacted Mallards name would be Anas Platyrhynchos which is the same as a wild mallard.
The only thing that ducks can lay are other ducks
Ofc thatβs what a lot of people do m. What would be wrong with it?
