can different birds cross-breed?

[Flock Runner]

i have chickens, ducks, and a male turkey. out of random curiosity can either of them crossbreed? probably not but just curious.
also, could a larger breed of chicken breed a smaller breed like a bantom? i know their both stupid questions but i was wondering because i've seen baldnecked chickens and ducks and bantom ducks! they were cool and all but i don't want to end up with a random mutant bird in my flock!

Chickens cannot and will not breed with turkeys or ducks or geese.
A larger chicken can and will have offspring with smaller chickens.
LOL no mutant weird things in your future.
There are no stupid questions. There are however lots of stupid answers.

The only possible cross is Guinea X Chicken or Pheasant X Chicken but it is rare.
