Hi, I used to keep ducks a long time ago, I’ve just started again. I have hatched 4 mandarin ducklings and two call ducks using a broody hen. They are all doing well, except one of the mandarins who is smaller than the others and doesn’t seem to have any energy and won’t feed on the meal worms and chick crumb. I’m very worried about it. If I try to hand feed it a meal worm, it tries a bit, but cannot manage to eat them. I’ve added some sugar to the water. Does anyone have any other ideas? The three other mandarins spend their time sitting on top of the hen, but he’s always underneath her or sometimes on his own. Any help hugely appreciated!
