Thank you, RC
Thank you. Now I am wondering about putting off changing out the Omlet coop to the larger version, which I was about to do, in order to not add any more stress to things. Maybe I'll wait until next week or later, or just store it for the winter. I was thinking of a few more chickens next year and the regular one holds 5-6 chickens, this one probably 8-10. It's similar in design, mostly just bigger, though the nestboxes each have their own space instead of one long rectangle. It looks much the same. Funny thing - it's assembled in the garage barn. The Spuds were walking through there (a home away from home - a safe preening / resting spot when I let them out to forage the yard) and Diane happened to go around to the front and stood there looking up at the pop door quizzically, tilting her head one way then the other!
I'm sure the dynamics will change some so there's got to be some stress. The Spuds had taken to following Popcorn's lead in foraging; Hazel is quite timid, always waits awhile before going out to join everyone, whereas Popcorn was always first to hop out totally gung-ho for exploring.
Thank you rm!
Thank you very much too!
@notabitail and
@Ponypoor - Thank you, Pony!

-- I understand & of course feel the desire to know, I am a high-information type person, yet it's the same with human health, for me that question is always weighed against what one loses for the test (money, time, a comfortable day with no pain, etc. - and here, whether you'll get the body back) - versus what can be done with or about the information gained. It's not clear that I'm going to get actionable information that will help the other four hens.
No one else appears affected with the same symptoms as Popcorn - loose stools, not eating feed and wanting instead to only forage, the urgency to sit in the nest box without laying. All the other chickens have normal poo, are eating well and are doing what's normal for them.
I never saw any worms in Popcorn's poo (I was fixing to do a fecal float test just for the heck of it but then she died). I was suspecting cancer. Possibly an infection somewhere, yet her poo looked normal: urates / solids proportions, no blood or mucus / cheesy stuff, good color though maybe consistently a bit darker (not black), which I expect given she wasn't eating feed but was eating worms/frogs etc. Just loose to very wet.
Hemorrhagic liver disease maybe? Would that cause these behaviour changes, increased water intake so loose-but-regular looking stools? She was hefty previous to this current weight loss, and always ate well and with gusto. Not clear what I would change for the flock, except ban treats, or try to further limit the treats a particular hen gets? (good luck with that!).
I have a call out to the vet near here that does necropsies for their information & thoughts. But I'm inclined to bury her with her sisters Peanut and Butters. Peanut I knew had cancer from the ascites and then vet xrays showing tumour; Butters it was never clear what was wrong except a digestive infection/trauma, either the main cause or concurrent with something else.
Thank you, Featherhead

Yes I miss her terribly. She was not a lap chicken, but a wonderful companion, friend & defender, & always up for an adventure. She didn't appear very uncomfortable and went about her day with energy & enthusiasm, so I am glad she seemed to be living the fullest life, right up until the end.
