trichomonas or coccidiosis

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.

What symptoms did the chicken have? Coccidiosis is fairly common, and treated with Corid or sulfa antibiotics. Trichomonas is also called canker, and it is an infection around the mouth or beak. Many people do cull for canker, since it can infect the whole flock and make them carriers. Some people use acidified copper sulfate 1/4 tsp per gallon of water for 3 days per month as a canker preventative when there has bee canker in the flock. You can treat for coccidosis with Corid or amprollium in the water if any of your chickens is acting lethargic or not eating.

Initially the only think I noticed is she appeared like the runt of the litter. She was just a bit smaller and slower moving than the others and I also noticed a little bald spot on her back above her tail feathers but the farmer had mentioned that and said she had just been picked on by a guinea hen. I watched her eat, drink and run around with the other in the run but eventually she was off by herself, standing up but with her head on the ground like she was exhausted and couldn't hold her head up. That's when I removed her, gave her a gentle warm bath, inspected her for anything obvious, dried her, and tried to feed her by hand but she was just really weak and couldn't lift her head. So I took her to the vet with the fecal sample and he said she had been sick for weeks (before I got her) and was very anemic (he commented on the coloring and appearance of her legs, feet and mouth). He looked at the fecal sample and said it was enteritis that had been with her for weeks. I thought he said trichomonas but now I'm second guessing what I heard. Maybe it was some other trichinosis? He also mentioned coccidiosis.

Thank you for the suggestions about medications to put in the water. Should I do something like this now for the existing flock as a precaution? Or maybe add some type of vitamin/mineral supplement to boost their immune systems?

I keep their coop and run immaculate. Every morning and mid-day I'm out there with a bucket and rubber gloves picking up their poop and making sure all is well. I refresh their water two or three times a day and make sure it's clean and the same for the feeders.

Histomonas is another protozoan infection that sounds like tricomonas, but is more common in turkeys (called blackhead by some.) It sounds like she could have had coccidiosis and enteritis, and probably was just very week, and thought she probably was just too far gone. Some chicks like that may always be sickly or not lay well. It might be good to give your flock a preventative dosage of Corid (amprollium, Ampromed) in their water. Dosage for prevention, not an acute outbreak, is 3/4 tsp of liquid Corid, or 1/2 tsp of the powder, per gallon of water for 5 days. If anyone starts looking ill, multiply the dosage by 3. After ward, and 2-3 times a week you can use a poultry vitamin in the water that contains probiotics. I have used Rooster Booster Vitamins With Lactobacillus, but most any poultry vitamin will do. A small amount of buttermilk, plain yogurt, and even many brands of chicken feed contain probiotics. Always quarantine any new chicks or birds for at least 30 days before combining them with your flock to make sure they seem healthy.

thank you for all the great info here. sorry so long since i posted. all is well. treated the flock with corid in their water as a preventative during the 'scare' and now they are all healthy and laying wonderfully.

Anyone might know if this is a sign of canker trichomonas? She is laying like normal and acting normal. Only notice it about 3 days ago

Welcome to BYC. It is possible that it is canker. other possibilities are wet pox, a fungal infection, or a tumor. Have you had canker previously? Does anyone show signs of fowl pox scabs on combs or wattles? Fish Zole ( Flagyl, Metronidazole) 250 mg orally per day for 5 days is the usual treatment. Acidified copper sulfate 1/4 tsp per gallon of water is commonly used once a month as a preventative. Here are some threads to look at:

Other than that sign on the beak all my chickens look healthy. Never had canker before. They are only 5 months old. We just introduced baby ducks that are 2 months. The Ducks were inside until about 2weeks ago. Now they all live in the same coop. One of the ducks sounded like she had a respitory issue but now sounds good.( Just trying to paint the whole picture) I have put acv in there drinking water from day 1 and garlic powder in their feed and now I have been giving fresh oregano and basil too. One new thing I just started was feeding them outside the coop in open containers with water also in open containers.

Also since all my 7 hens and 2 ducks all drink out of the same bowl, I would assume to treatment them all. And for acidified cooper is it natural or any side affects? And does it cure as well as prevent?

Sorry one more thing. it looks more like a built up hole/ crater with yellow inside and as you can see blk underneath the skin.
