[KWAK]

Sunday one of my friends brought over 2, 2 week old muscovy ducklings who's mom wasnt taking care of them.
Both of them are way smaller then any 2 week old ducks I've ever seen.

today both of them are acting strange and wobble a lot while they walk but when they trink their whole heads wobble every where.

whats wrong?

What are they being fed? Are they being kept warm enough?

They may have infections, it is hard to know from what you say.

They need clean water 24/7.
They need balanced food - waterfowl starter if you have it, or chick starter with sprinkles or brewer's yeast or with 100 mg of niacin dissolved in a gallon of water each day.

If they have an infection, they need antibiotics and should see a vet or someone who can help them.
