Well, I'm currently having my first experience, hopefully my last, with this... One of the new chickens i brought in with a group of 4 others was a bit lethargic. She's spent a total of 8 weeks with the others before I got them, and a total of 4 days with my existing flock. I removed her yesterday and placed her in a kennel. Took her to the vet today with a fecal sample and he said it looked like trichomonas but then mentioned coccidiosis as another or additional possibility. So, he recommended euthanasia as she was just too far gone he thought and I agreed. I feel horrible and now panicked about the rest of the flock. I'm headed out to the coop and run right now to clean clean clean! She had not spent anytime lose in the coop, had always been in the kennel with the others, but the others have been free in the coop and run... So I'll just keep a close eye on them all going forward. Any of your experiences or suggestions of course are welcome.
