I'm not sure of the type of ducks I have, I have 8 little yellow ones nd 2 little black n yellows... Could the little black n yellow ones be a mix breed? I know I should of asked but after a dog eat my pair of call ducks, I really didn't care... So I'm new 2 the duck business ! Okay & now how much do you feed little ducks? I leave food out day & night open free to eat... & it's like boom over night they grow unbelievable... Sorry for asking all the questions but I just thought it's better then adding to post... Thanks
