So ive got a duckling that is just a few days old. Yesterday he was doing well, moving around, eating and drinking but this morning he has stopped eating, drinking and has very little energy (he fell on his back and barely moved his legs to get back up). He has been sleeping all day and looks very tired while the other ducklings are peeping and running around and eating/drinking. He seems lethargic and unwell but I am not sure why. They have spent all their time in the brooder and havent had contact with other ducks. He also gets very dry eyes but that has been happening before today so am not sure if that is related. Unfortunately our local bird vets are shut so I would like to figure something out to help him become more comfortable. There was also an incident last night where him and one other duckling were regurgitating their food and foaming at the mouse/nostrils which has since seemed to stop. Can anyone help?
