Hello all, I need help and fast! I’ve lost a lot of wood ducklings to what looks the same thing. I only have two left and one doesn’t look so good. If I pick him up he’ll pant and breathe very hard, he’s a lot smaller the the other, and is just not looking so good in appearance. The live outside with a Muscovy duckling that’s a lot younger and a Indian Runner duckling. They have access to dry mealworms, chick feed, and water. Thank you for any help!!
