I have a 1.5 year old Saxony who just recovered from a niacin deficiency. She has been acting 100% normal until last night when she let herself in the duck house which is odd and this morning she did not come out. Her feathers are ruffled, she wont stand, she has a half closed weepy eye, her vent is swollen, purple and protruding a little and she has some leakage of diarrhea around her vent. She makes a strange squawk noise occasionally, idk if its a cough or a whine from discomfort. Those are all of her symptoms. Any thoughts??
