I have an 8 week old mallard and was wanting to know the gender! I read that all mallard chicks start with the female coloring (brown) and if its a boy you'll notice green on its head. Is this true? I have two other ducks (not mallards) that are male and female so I know what the quack sounds like. He/she is quiet but still has his/her peep. He/she has more than 1/2 of his/her feathers. I am noticing a little green in the head feathers. Boy or girl? Thanks
