Hi all, I'm a pretty new chicken person, 16 months into this. One of my birds is a Creme Legbar. We raised her from a day-old chick starting in Feb 2020. She and her two flockmates were outside from around June in their coop. She started laying in July and was going well until September, when she stopped. We are in San Francisco so the climate is mild but I attributed this to molting and/or wildfire smoke and/or fall and didn't worry too much. But 9 months later she has not restarted and gradually has seemed a bit slow and lower energy than the others, always last to hop out of the coop to forage, etc. In the past few days she has seemed more lethargic than before. She does a lot of standing around with her feathers a bit puffed out and her neck short (see pics). Her comb is now pale. She will still get interested to move for food but is not otherwise very active. Have not been able to observe poop but her crop seems okay. Vent looks okay from outside but I haven't done an internal check yet (but again, no eggs since Sept). I'm unsure whether she is just "not thriving" or if there's something more sinister going on. Have started to wonder about coccidiosis after reading about it here and am probably going to purchase Corid tomorrow to be on the safe side. I can't think of any other changes the last few days other than one of her flockmates going a bit broody. If anyone has any thoughts I'd appreciate them. Thanks.
