I recently bought two mallard ducklings from a Tractor Supply Co. here in New Jersey. They did not come marked in any way (no back toes missing, no bands, no pinioning) but I saw these websites after getting the ducks: http://www.law.cornell.edu/cfr/text/50/21.13 http://cfr.vlex.com/vid/exceptions-captive-reared-mallard-ducks-19894607 http://federal.eregulations.us/cfr/section/title50/chapterI/part21/sect21.14?selectdate=1/2/2013 Do I need to mark my ducks? I don't want to get into any trouble for owning them. I have the receipt from Tractor Supply, but it is not specific and I did not get any paperwork from them about the ducks. They're probably 4 weeks old (not over 6 weeks old) and I really don't want to pinion them or have to remove a back toe. Should I band them? If I should band them, then where would I get the bands from? Do I need to get the bands through the state? Thanks! All help is appreciated!
