SERIOUSLY STOP SAYING CHICK START IS FINE FOR DUCK. IT IS NOT!!! ESPECIALLY IF ITS MEDICATED. chick starter is called CHICK for a reason. the protein and nutrients aren't the proper amount or quality for duck. they will develop deformities and get sick. feed them bugs, small sea shell, crush up earthqorms, make your own starter. for the first 2 weeks only. then use a feed or do whar I do, feeed them real food! organic hardboiled eggs, organic tomatos amd fresh greens. stick it in a food processor n let them feed wit plenty of water. if you use medicated chick feed your duck will not only develop bone, height, weight and allergy problems as well as bone issues but it tends to over eat. and if u overeat medicated chick food for duck I mean...do I really need to explain?? n if u people are just plain lazy to do research or even just feed them howw I suggest, which seems u r lazy, just buy DUCK STARTER FEED 20-22% get organic so it osnt genetically modified and u nor your pets will get cancee, tumors or other diseases n complications. seriously I know we live in America, the land where all information is free, available and resourceful but its 2012! use the info out there before the feds take it away! stop sleeping, its this country who are the guinea pigs and when u spread he says, she says without research or experience then u r no better then those banksters ruling u while u sleep. for your safety of course.
