mandarins can cross breed it just takes a lot of work

Mandarins will cross with call ducks conditions have to be just right . And you may get just a few offspring so it may not be worth the time.

NO WAY. THE CHROMOSOMES DO NOT MATCH. TAKE 101 OVER AGAIN.

No, mandarins can't cross breed because of the chromosomes. Maybe your mistaking it for the wood duck? If you DO seem to find a cross mandarin and call then please post picture proof. You won't find a cross though so don't stress.
