Hi I know this is a chicken emergency forum but I need help with my 2 week old duckling I noticed this morning he is croughing or trying to He keeps opening his bill and making a strange coughing sound. I haven't taken him out of the brooder yet as I don't want to tramatize him but I don't know what to do. I only have sulmet,vitamins and FishFlex on hand as antibotiics. Whast can I give him ? He hasn't gotten cold as I have a heat lamp in the brooker and its reading 82-85 degrees. He is inside in a very warm room Any response would be appreciated.
