Welcome. While watching her, is she drinking enough? Does she have clogged nasal passages? is she actively eating and swallowing food? is she overeating? and have you checked for an airway obstruction? If you can rule those out as well as stress and heat, then there may be a medical issue, perhaps lungworm or a respiratory illness.Hi! My name is Matin, I'm a first time duck owner. I have 5 ducks with varying ages. I have 3 that I hand raised they are around a year old, and 2 that I got from a friend, I believe they are around 2 years old.
I live in Australia so the weather is quite volatile, just to give you an idea of the weather, it has been fluctuating between roughly 15°c (59°f) and 30°c (86°c) recently.
I have noticed one of my female Rouen ducks lightly panting when the others aren't panting. I have observed this a few times. They have free access to drinking water, swimming water and food. They also have plenty of shade.
So my question is to those who have more experience, is this a cause for concern? She seems healthy overall. My theory is she might be slightly broody, which would explain her being hotter than the other ducks. I noticed she was laying in her nest during the day, they usually lay at or before dawn so I think she is starting to go broody.
