I don't know about apple cider sweetie but it looks like Miss Lydia found a link. I think you just watch and take care of JoJo like you are. Hopefully the sweet drake will find his ways or he just could be quirky and not do duck things lime the others.Yea he eats fine. Charlie's a pig and JoJo is submissive but he's getting enough. A lil bit ago I had JoJo and charlie in their pool and my daughter in her own baby pool out in the yard. They were loving it. The ducks were crazy happy, same pool as always but they were frantically going under water and in fast circles, etc. It was hilarious. Point being Charlie has done this but not JoJo. When they were soaked they would fluff out their feathers and spread and flap their wings, first time for JoJo and I was so happy for him especially since it was worrying me and I just mentioned it. Since all the advice, he's been great. No episodes but its only been a few days, I'm praying he stays strong! So far he's good! Im trying to find out why people give ducks Apple cider vinegar, I'm new to this and I have no idea. Do u know?
