I've recently heard that due to the impending muscovy restrictions, that they are requiring all muscovies to be pinioned, have a toe removed, or be tattooed. This is coming from a person in Ohio who is now getting rid of all their ducks. I've since emailed the FWS about it (again) to see if they recommend tattooing. I've already emailed them for a direct response to my questions about the law, as I Well, I wouldn't mind tattooing my ducks - might actually be a good way to tell some similar appearing ones apart, or for permanently identifying my geese as male and female - once I figure out how to sex geese. I'm imagining you simply tattoo the webbing between the toes, but I'm wondering if anyone has done this or has pictures of 'proper' placement. Also, how on earth would one tattoo the TEENY feet of hatchlings? Would you just have to wait and put off their sale a few weeks until they're large enough? I was thinking to just tattoo a single letter on one of their feet at a young age - that seems like it would fulfill their permanent id requirements. That is, if they start regulation... I already tattoo rabbits on a regular basis and goats rather regularly, so doing ducks/geese probably wouldn't be THAT hard.
