My 2 year old (ish) Banty Hen is acting drunk, she wobbles around and is not eating or drinking on her own. I can coax her to gobble down a chopped up grape (or two). The last three days she has only eaten two grapes per day. Which is very unusual, she is typically a heavy eater. No swollen crop, I've moved her inside and she poops maybe once per day. I've attached a photo. Any thought??? She is progressively getting worse, she was able to groom herself on Monday and this morning she was not able to take a step without falling over. Her pupils are also looking strange, the get big then get small even if there is no change in light. She just stares off and her pupils dilate then shrink back. It's all very strange. Should I give her antibiotics??
