Some friends gave us a 14 year old doe about a month ago. She was a little overweight but seemed to be in overall good health. A little over a week ago I gave her some cydectin since her eyes looked too light and she has seemed fine until I checked on her today. She's been a little droopy and her eyes (tear ducts?) are swollen. See photos, one was taken a few weeks ago and one today. What should I be doing?
