We just lost a Seabright chick last night that was about 3 weeks old. She had been fine all the way up to that point, was very friendly and would walk onto your hand to be picked up. We took them out of their "home" yesterday to change the bedding and then put them back. Within several hours she seemed lethargic, though she did take water from a syringe. I noticed that she kept scratching her face, something I hadn't seen her do before. We monitored all night, but unfortunately we could figure out the problem to save her. I was researching online and found your thread. I was wondering how old your chick was when you lost it and if you had any similar situations since. We have one more smaller chick (a Seabright) and would hate to see anything happen to that one. Thank you.
