Black Austrolorp, just under 30 weeks. Started laying a month ago. About 3 months ago, I started noticing her holding her mouth open at night time on the roost. Not every night but maybe 2-3 nights a week. I thought about quarantine but the next morning she came running out, eating and drinking fine. We've carried on like this for the last few months but today and yesterday got up to 95 degrees and she seemed to be having a hard time but made it past Sun down. About 30 mins before everyone usually goes to roost, she started making this high pitched distress call, 20 seconds apart and kept doing it all the way to roost. She did it for 2 solid hours on the roost so by 9pm I brought her in the house where she will be residing for night. In between calls, she would sometimes make a honking noise with hard out breaths. It was very strange behavior. I checked everywhere, no predators and she was in her normal spot so it wasn't a territorial call. I'm stumped. It's not gape worm because she's been honking and out breathing for months now. Respiratory? But wouldn't the rest of the flock caught it by now? Is she just a weird bird? I'll try to upload a video I took of her in quarantine tonight. She stopped doing the call but is still honking and out breathing with mouth open. Any clue, anyone?
