Don't think it is egg binding as it has been going on since spring it seems. I sure she would have not made it this long with egg binding am I correct in my thinking. I just started to use an anti-fungal today and I have been washing her vent area almost daily. As well as yogurt and garlic in her water. We hope she gets better. Thanks for you advice.

Vent Gleet is the most likely candidate for the discharge, if it has gone on too long, it can cause the listlessness, but if you have been treating her, she should have improved at least slightly.
You may want to take a fecal sample to your vet to have a fecal float test performed. They can test for cocci, worms and infection. If it is only Gleet, then they can prescribe an oral anti-fungal to help knock this out.
Having a hard time walking, she may also have some type of internal laying/reproductive disorder as well. Something like Egg Yolk Peritonitis, Salpingitis, cancer or tumors are common causes of listlessness, weight loss, difficulty walking, etc.
How does her abdomen feel? Normal, hard, soft, fluid filled, etc.?
