For my upcoming website store for all things ducky, i've decided to size things (diaper harnesses, walking harnesses, wing wraps, ect) based on duck weight classes... I can't seem to find a definitive list of breeds in each weight class, i i was wondering if you guys might help me out? here's what i have so far- bantam- (x-tra small) calls, black east indies, silkies, austrailian spotted, mini appleyards, mallards, wood ducks, mandarins, snowy mallards Light weight- (small) Indian runners, bali ducks, khaki campbells, welsh harlequins, magpies, abacot rangers Medium weight- (medium) buff orps, golden cascades, hook bills, cayuga, swedish, crested, Heavy- (large) saxony, aylesbury, rouen, muscovy, jumbo pekin, pekin, appleyards not sure- anconas, Do you think this list sounds good? I'm thinking bantams are 2lb and under, lights are 3-5 pounds, meds are 6-8, heavy 9-12. I am also thinking of adding an XL and XXL sizes to include geese- XL- Male Muscovies, Sebastopol, Pilgrim, American Buff, Pomeranian (12-15lbs) XXL- Toulouse, Embden, African (16 and up?) And what about geese? Are the light class geese about the same size as larger ducks? So could a chinese, roman, egyptian, or canadian be about the same size as an aylesbury or a female muscovy? i don't have geese so any input on them and their sizes would be greatly appreciated! I'd also like to include turkeys, peafowl, guinea fowl, quail, pigeon/doves etc... but that will take some research on their sizes and breeds... i might offer those as a custom order. Anyone with any ideas let me know. i might just have to experiement with people if they ask, maybe offer a harness at a low price if they give me measurements and let me know how it works out... I'm also wondering about foot sizes, I know bantams have typically smaller feet and don't muscovies have much larger feet than say a pekin?
