Hello all! Later this week I am picking up four Cayuga ducklings, two for each of my step sons. They will be "raising" them and yes, I will be closely supervising I am able to tell all of my ducks and chickens apart, but the boys are 8 and 10 and I see many a fight over whose duck is whose in my near future. If you have ever had boys....you know this to be true. Is banding their legs with those color bands the best solution? Is it safe? I've never used them before so I'm looking to see what the cons are, if any. Thank you!!
