Help me diagnose

[Beaker99]

I've got a 3 yr old hen that is lethargic, with mucous, yellow droppings.
She still eats and drinks a little. She walks with tail down and seems a little wobbly on her feet.
I examined her and found nothing out of the ordinary. Crop and belly feel fine. She was vaccinated for maerks as a chick.
No other birds are ill. No change in food.we have had a TON of rain lately, if that matters.
Ideas?

Inspect her for lice/mites, especially around the vent area. Use Permethrin dust to dust her if you see external parasites.
I recommend that you worm her with Safeguard liquid goat wormer.
When was the last time she laid an egg?

No mites, I checked. I already wormed her. No idea on the egg. I have six that look identical and I work full time so..
