Help - eggbound or something else?

[longday]

I have an Australorp, about 6 years old. For about the past 24 hours, she's had this odd posture. She seems reluctant to move around a whole lot, but is still moving, and seems possibly interested in food. She's got dirty feathers around her vent, and this has been a somewhat ongoing issue. Her third eyelid closes often like she's in pain or discomfort (obvious also from her posture).

She's part of a flock of 5; all others seem healthy. Any suggestions?

I would grease a finger and feel for a egg, If I do not feel a problem I would start her on tylan50 1ml oral twice a day and see if she perks up.
