Oh yes so busy trying to figure out the other completely slipped about the calcium, thanks for catching that. And yes pics of ducklings and leg and foot of one that was injured please.Can you post pictures of the ducks? Hatcheries make mistakes. And ducks can be hard to sex at this age. Do they both quack? Or does one sound raspy? I would take the calcium out, where is plenty in there feed. They don't need any added intill they lay. I would add brewers yeast, which if they where lacking can cause leg problems.
