I have a hen who presented with diarrhea and puffed up/lethargic/hiding in corner yesterday. Totally fine the day before. She is still eating and drinking but very little. No mites, crop is good, belly not squishy. Not egg bound, I checked. She's about 5 years old, doesn't really lay anymore. No sneezing/discharge. I started corid and dewormed (safeguard paste) yesterday. My vet sends all fecal samples off to Cornell so I would not get results any time soon due to the christmas holiday. Since I haven't seen any improvement, I'm concerned if I keep up with the corid I'm depleting vitamins she probably needs at the moment, plus with her age and the fact she has been in the same area for 5 years I know coccidia is unlikely. They received clean fecal sample this summer. But, it has been raining here a lot and I know coccidia can cause issues in adult birds if they have underlying health issues. Question is, do you think the corid is causing more harm than good? I gave a dose today (drench), if I stop could I start vitamins today or do I need to wait until tomorrow? Any suggestions on what else can be going on by looking at the poop/stance? Could EYP be a possibility if she's no longer laying?
