Hello everyone. I'm looking for some help on a possible diagnosis of a sick sebright pullet. She started off doing a little gaping and stretching. Then she started gaping all the time, with zero noises while gaping or breathing. The videos linked to this thread is about day 5. She got a soft soft swollen crop and started to be still. She ate and drank on up till yesterday when she passed. I had put her on safeguard thinking maybe gapeworm at first. I don't believe that was it. She was 12 weeks old. I have a brother to her possibly getting it as well. Just started doing a little yawning like she did at first. Eats, drinks and gets around fine. Thank you for any help or opinions.
