I’m a new duck owner. I love them. We have a 17 week old f male Pekin. She’s been acting strange for 4 days. We noticed that she started holding her head down on her chest. She wasn’t eating and it almost seemed that her beak didn’t work. She lost her quack. I found a vet about two hours away that was willing to look at her. She checked her droppings, nothing abnormal. Her temperature was normal. Her body felt normal and vent was clear. She thought her crop might be plugged. She flushed it and suggested we do the same. It’s been a few days. She eats a little now and quacks a little. She still looks like a pelican. Her head tucked on chest as she walks around. Does this sound familiar to anyone? Crop?
