I have 6 Rouen ducks that are 7.5 weeks old. I am preparing for them to be let into our pond here shortly (whenever their feathers are done coming in), and I was considering putting some zip ties on their legs to be able to identify them (mostly so our niece can tell the difference between them). At 7.5 weeks old, would that leg band be a good size for them to wear permanently? Or would I need to keep watching them to make sure their legs don't grow to big for the ties? I'm concerned that their legs might keep growing, and I definitely don't want to have them get to tight. I'm also trying to avoid chasing them down after they are free range to re-do their bands, so if that is the case, what would be the best age to put the bands on? Thanks for any help!
