I just picked up this cutie for a brooder mate for my Elizabeth. I have some concerns.. she’s never been handled, her living conditions were a wire rabbit cage with 5 other ducklings, with a dry duckling waterer, definitely nothing to rinse her nose and I didn’t see a food dish anywhere. The conditions were not.. ideal. Anyways, she has a runny nose, sneezes and shoots snot everywhere. When she opens her mouth it almost sounds like she’s hissing but out of her nose. Her poop is yellow liquid. I know she’s not healthy. I have VetRX and Nutri Drench. Not sure how to use them correctly and google is frustrating me. Suggestions on what I should do? Is she contagious?
