Gladys, the last of our original trio of barred rock hens, has been increasingly lethargic over the past week or so. She is eating and drinking fine. We have seeing her "resting" more during the day by sitting down in the yard. When I returned from a 5-day trip to GA, my partner mentioned that Gladys had a weird bump on her breast bone area and her chest area is swollen. When I went to the coop tonight...she didn't attempt to move away from me. In fact, she let me pick her up and hold her. I noticed a callous-type circle on her breast area and her chest seemed swollen. She's had labored breathing for a while, but it didn't seem to slow her down. Today was different. The callous-spot didn't feel hot to the touch and she didn't seen to be in visible pain. Any thoughts on how to proceed? I can take get to the vet this weekend.
