What the DUCK!!

OMG!!
Its a mutated duck!!!! All I would like to know is how the hell a duck and a goose managed to "get it on" AND what the bleeding hell would it be called??
Today was a weird walking day for breeds and breeding - take a look at the boyfs blip and you will see what I mean!
The "Guck" was massive but was following its duck mates around quacking in a deep goosey grunt!! Poor fella xxxMy boyf's blip lol!

Just to say this blip is 100% genuine!!!
