Greetings
Mayabarabi,
You did a great job, examining your hen, Podoke!
I could tell you not to worry, but, we keepers do worry anyways, when our precious chickens get sick.
A hen can expel a watery poop when they are frightened. For instance, when you suddenly pick them up, especially at night.
This is why you should always isolate a chicken, that you suspect is ill. You can observe them and the kind of poops they are making when they are in a crate, and calm.
Also, you need to have nest boxes for the hens. How do you collect eggs? Do they have a coop to live in?
You report: no respiratory symptoms, no lumps or sores, no mites, the vent is clean, the feet and legs are clean.
She may already be getting better. But, don't rely on this, a hen can suddenly go down hill very quickly and die. Here are the things that concern me about your 1.5 year old hen.
- Watery diarrhea?
- a shelless egg found
- excessive water intake
- low appetite
I believe she has an infection. It is highly probable that the shelless egg was hers. That may have happened because her body's resources were fighting infection. I cannot tell you what is causing the infection, or if it is viral or bacterial. Being out in the rain without shelter is not good. Her symptoms are not consistent with worms. But, I would have a fecal float (poop test) test done on the flock to see if it could be a contributing issue.
What to do?
- At this point, I would keep her separated, out of drafts and cold.
- Provide good nursing and supportive care: keep her crate clean, provide feed, fresh water.
- Diet: offer cooked egg, diced meat protein, cooked or fresh vegetables or greens, cooked whole grains like (brown rice, wheat berries, barley, oat groats, etc.), a bit of diced fresh fruit.
- Administer a vitamin supplement for poultry
- Add electrolytes to her water for a day, two days if diarrhea continues.
Medical care: If she was my hen, I would administer a broad spectrum antibiotic.
If her infection is bacterial, the antibiotic will take care of it. And, if it is viral, then the antibiotic will protect her from any secondary infection that may come up. It is common for a sick chicken to have a couple of things that are causing illness. So you will have to be vigilant with her, and, the rest of the flock. If your girl has something infectious, they may have been exposed, or not.
Remember to provide three days of a probiotic supplement, for poultry, after any antibiotic course.
I can tell you really care about your chickens. It takes a few years to learn how to better manage and care for chickens. They are so funny and entertaining, plus they give us all those great eggs! But, when they get sick...it can be heartbreaking and very stressful, if we don't know what to do for them. Ideally, it is good to have a veterinarian that can diagnose and do tests on the sick chicken. But, sometimes there isn't one nearby or a keeper cannot afford one. There are also, good books that will help you learn how to care for your sick chickens.
Since I do not know what your location is, I cannot advise on where to get medication. But, if you need help with this, just let us know here on BYC.
These are my thoughts on your hen's situation, I hope I have been helpful.
Other members will give advise, please consider these too. There are many great chicken keepers here on BYC, with a lot of good experience.
Please keep us updated on your hen's progress.
God Bless and peace to you.
