Sick red hen! Please help!

[brinsleyxmercedes]

My poor hen has been acting very strange the last few weeks. She has her feathers ruffled all the time, missing feathers on her lower back. She has been standing in one spot for hours, sometimes on one foot. When I enter the pen to check on her, she jerks her head around and sometimes walks and pecks as if she's nauseous. I noticed today, on a colder day, she hung under our birds of paradise bush in the corner of the pen. Her eyes and nostrils are a lighter colour, and when I was putting her to bed I noticed a pale blue-green mold like on her ears. She has poo on her bum, but that's not abnormal when she's well. Her comb is up and a normal red with no other markings.

My other red has feathers missing from her neck, exposing the neck. However, she and the other 2 breeds have been acting normal.
Does anyone know what could be wrong with my poor chicken?! Please help!

Note: i took photos of her laying down today, just need to figure out how to post.

Missing feathers are normal this time of year because it is molting season. However, for other symptoms- check your birds all over for parasites. Check her crop, first thing in the morning- is it empty? If it is full in the morning, or squishy or doughy feeling, then a crop issue could be the culprit.
Have you dewormed your birds recently? How does their poop look?
What food are they on?

Have you dewormed your birds recently? Can we get a clear picture of her poop? Do you have medicines and supplements in hand like electrolytes and corid ?
