I have attached some photos in the reply. Sorry - I had tried to do that in the original post! She’s looking scruffy and her wattles have gone dull. But still eating and drinking.
Thanks for your help.
Bloody stool? Poop photos may help!
Any feather bombs in the coop? This is normal behavior for a molting chicken, here are symptoms:
Usually a little over a year old (almost 99% of the time)
Not laying eggs
Scruffy
Less active
None or less egg laying
Slight poop change
Pale face
Signs in chickens with coccidiosis (symptoms will overlap)
Scruffy
Pale face
Possibly droopy, dragging wings
Less of no egg laying
Huddled in corner, not just less active, lethargic overall
Poop changes often include bloody stool and lots of foamy, light brown poop. Note that cecal poop (foamy light brown and very smelly) is a normal occurrence in all chickens, but happens every 10 days or so, not daily. If it is daily, something like coccidiosis may be to blame.
Heres something i like to do that helps me a lot. Bring the chicken inside if you can, if she lays down, doesn’t want back outside and just seems even worse, she is probably very ill. If she seems like she slightly wants back outside, starts screaming, or doesn’t get worse, she is probably molting.
Also note this isn’t a for sure thing, but it will help. Chickens hide their symptoms so by the time its noticed its often much farther along then it looks. She will hide it to not get beat up and excluded from fellow flock mates, so when separated, if she gets very lethargic, that is a sign something is up.
Worms may also be a possible issue to inspect.
