I have a drake that I noticed this morning with a swollen chest. I have cornered him and felt his chest and it feels as something is in there although its not extremly hard. I noticed him spitting up today and moving his head from side to side and drinking lots of water. If it is impacted does anyone have any info on treatment for ducks? All I seem to find is treatments for chickens. Would it be the same treatment? I would like to try to treat it myself before having to take him to the vet.
