I have an Americana hen who is just over a year old. She is generally very active and loves to eat. We recently had really hot weather- over 100 degrees. She had plenty of shade and water but started acting lethargic about 1 week ago. She was standing in the middle of the snacks just sleeping. She then was laying down in odd spots in the yard barely moving. I took her into my garage with a fan to see if she just got overheated and kept her there for a few days. Now it appears one eye stays open and the other one opens and shuts. At first I thought she had an impacted crop so I was feeding her oil in her water and massaging her several times a day. Now she just appears to barely eat at all and drink occasionally. She is still jumping over my fence (neighbors allow her to visit) and still roosting on top of my shed. She started out being lethargic and then making a weird motion with her neck and opening her beak like she is choking. She is still doing this on occasion but last I felt her crop it was empty. I don't know what to do for her- is this a neurological issue? She doesn't have any crust or congestion around her eyes or beak. She is no longer laying eggs and doesn't appear that she needs to- (stuck egg) because she isn't going into the nest to lay.
