This is one of my hens. She is a leghorn and delaware mix. She was a very good layer, and rarely skipped laying. However, she was going through her first molt so she stopped. (In the picture you can see she’s still growing her feathers back) We gave her a quick bath yesterday to clean her vent and under the wings because one of our flock members has lice so we wanted to quickly treat the whole flock even thought she acted completely fine. Today, it looks like she’s struggling to breath, and she just sits down a lot on the dirt. Her butt and vent is pulsing, and it also seems like her stomach has no food in it like she wasn’t eating today. She also pants. These are pictures of her vent and her stomach. She walks normally though.
