EE Hen Sick After Laying First Egg... Please Help!!!

My little buff EE hen tried to lay her first egg yesterday and the result was egg shell, white and yoke all over her rear. She was outside later, taking a dust bath and doing her chicken thing, eating and drinking. Now she is standing around all puffed up and won't eat. I brought her inside and gave her bottom a bath and searched inside her vent. Found no shell, etc. She is now in my bathroom in a cage with towels and food and water. She just stands there and won't eat or drink. Any ideas? Please?

1) What type of bird , age and weight. EE hen.
2) What is the behavior, exactly. Not eating or drinking since yesterday. Puffed up feathers.
3) How long has the bird been exhibiting symptoms? Today.
4) Are other birds exhibiting the same symptoms? No.
5) Is there any bleeding, injury, broken bones or other sign of trauma. No. Just the broken egg on her bottom.
6) What happened, if anything that you know of, that may have caused the situation. She tried to lay her first egg.
7) What has the bird been eating and drinking, if at all. Organic laying mash, scratch, well water.
8) How does the poop look? Normal? Bloody? Runny? etc. Poop is formed, a bit loose maybe and kind of a rust color.
9) What has been the treatment you have administered so far? Bath, brought inside. Keeping warm.
10 ) What is your intent as far as treatment? For example, do you want to treat completely yourself, or do you need help in stabilizing the bird til you can get to a vet? Will see vet if no improvement.
11) If you have a picture of the wound or condition, please post it. It may help. No wound.
12) Describe the housing/bedding in use. Straw in coop and free-ranging outside. Now she is in a big cage with clean towels on the floor until she is completely dry from bath. Have heater in room so she won't chill.

If anyone has any idea what to do, please respond. She is the sweetest little hen.

 

I gave her some mashed egg yoke and doctored up her water. She won't eat or drink. She is looking around and moving a bit though. Sure hope she gets better. Thanks for the tips and encouragement.

 

Put my little EE hen out in the sun this morning and she is looking much better. Dust bathing, pooping up a storm, eating a little more and drinking lots of water. Any ideas what might have happened to her and how to keep it from recurring?
