If she's egg bound, she's not going to seem perky and normal.  It's possible she's taking a break -- were there any changes in her life recently (different feed, a new bird being introduced) because that can throw them off for a couple of weeks.  I had an egg bound RI Red over the summer, and she was completely listless and wouldn't eat or drink; she just lay in the nesting box, panting.  I tried the warm bath and all that, but I had to go in and get the egg (nothing like violating your chicken).  She didn't actually complain that much, and it can be done by one person, if you need to resort to that, but it doesn't sound like that's the issue.  
BTW, she's fine now and is my best, most consistent layer.  So if you do have an egg bound bird, don't necessarily think that's the end of the road for your chicken.  There are a lot of sad stories about chickens who die after being egg bound on this forum, which makes things seem like they have to end that way.  
If you feel like you need to do something, you can take a syringe of warm water (the kind you get at a regular drug store works fine) and squirt it into her cloaca.  If anything eggy looking comes out, then she may indeed be bound.  If it turns out you do have to go in, make sure you lubricate your finger first, and go in VERY slowly so that you don't do any internal damage or break the egg.
It would be much more helpful if they could just tell us what's wrong, or that nothing is, and quit worrying.  Anyhow, good luck.
