My call duck hatches out a week ago. She will drink water but it's like she just doesn't understand the concept of food. She has crackling sounds when she breathes which a lot of mine that hatch out tend to do that (chicks). Also, she chirps and cries a lot. I know her being solo may have something to do with that but I wonder if it's more. I can hold her ans keep her warm and she will still cry. Can you please help me out with what her problem is? She will settle down eventually but she is not coming along like I would like. I have hand fed her. Any suggestions???
