I have a bantam RIR hen that has been acting funny lately. So I seprated her and have been watching her. After a good look over, I noticed the area around her ears is swelled. She walkes around like she is drunk and when I pick her up she has a fit and acts like I am tipping her or something of the like. She is eating and drinking and pooing fine. At first I thought it was impacted crop, but it feels like nomal. Any ideas? Anything would be great! Thanks!
