I just baby chicks and ducklings a couple days ago. I have been keeping their bedding very clean, they are under heat lamp, and have starter feed, and water. Today I went to check on them and noticed that the baby duckling we call blondie is not doing so well. I had them out it the yard yesterday for about 15 minutes in the sun. Today blondie who usually runs from us is hardly moving when we go to pick her up. She is being really calm, and seems sleepy. She is trying to make peep sounds but all that happens is a puff of air and liquid comes out of her nostrils, eventually after trying ling enough the faintest peep cracks through. I don't know what could be wrong with her, any ideas?
