I wonder what causes the iris to change color as the birds mature. Very interesting. Is it sun exposure? Or just a factor of maturation? I just know I have never seen a blue eyed duck before. I am sorry to hear Kiwi died. I don't wanna know how it happened. But it is so sweet how Lilac took them on as her own and how they follow her and all gang snuggle with her. Are Muscovies the main tail wagger ducks? I've seen other duck/mallard videos before but they didn't wag like these do. It is sooo cute. @Miss Lydia has posted a few vids with her Opie and he wags all the time. Lilac and some of the kiddos were doing it quite a bit. It seems like they are happy and excited. I would love to see those next videos you have. The mud one would be awesome.
