Watery poo with some brown solids in it. What should I do?

[GRB73]

I have a six-year-old white Wyandotte. For the last few weeks, her poos have been very wet. Lots of liquid white with brown solid in it. No blood or yellow. Just liquid white and brown. She does have normal, though soft, poos throughout the day. Her poos are the most liquid in the morning. She had a fecal float several weeks ago, and all was good; no signs of parasites or bacteria.

She is very active, still eating and drinking, and lays about one egg per week. She free ranges several hours a day in my garden. I wish I could say this is an isolated incident, but we go through this at least several times a year with her. I've tried adding vinegar to her water, one tablespoon per gallon, for 5-7 days. I've also tried treating with Rooster Booster. The watery poos keep coming back. She may need an antibiotic, but I don't want to give one without good cause.

Has anyone else experienced this? We have an avian vet about 30 minutes away, and I will probably make an appointment. I'm just wondering if there is something I could be missing that I could try on my own. She is a very loved, sweet pet chicken, and I want to help her.

Thanks in advance for your assistance.

What should you do? Wait or have a fecal sample read.
There are so many types of normal feces.
Don't give antibiotics till you know exactly what you are treating.

Changes in weather, consumption of water...
There's numerous things that can affect the consistency of poop.

She's eating/drinking/very active, laying an egg, had a fecal float (no parasites). If you feel she may need medication, then ask your vet to run a gram stain to see if there's infection.
Ime, very active/eating/drinking, etc...a hen doesn't need antibiotics.
