upthecreek, you were right! I followed your instructions and gave my hen about 3cc of cheap wine. That was about 3 pm.  At 7 pm, she began pooping! It looked as though it came out with a little force because there were droplets 2 feet away. I fed her some turkey rice baby food and some applesauce 2X before I turned out the light. This morning her crop appears empty!  I am just thrilled! I'm surely going to keep this info ready in the event this occurs again. And, I'll have the wine on hand then, too! I'm interested in hearing what cnj experienced after give wine to her hen.
Meanwhile, ultrasol, I want to get some of the Harrison's food and have it on hand, too. I'm learning that you just never know when you may need something and when it's harder to get, there could be a problem. Question:  I don't recall seeing how many ounces are in their packaging so I don't know how many to order.  If you have a moment, would you mind giving a suggestion. 
So, today I will keep feeding soft food, adding some bread/oil in later today. Tomorrow, I will keep her inside as well, slowly beginning to get her back up to speed. Depending on how she's doing, Friday is supposed to be really warm so I'd like to return her to her own home then.  I would think she would be a "target" for the other two hens so maybe I'll have to remove them for a few hours while she gets her land legs back!
Thanks again, everyone. I'm really thrilled over this. These are my first hens, not that I will love any subsequent hens less, but you know what I mean. My farm memories from childhood did not include have chickens that were sick. Maybe I just didn't notice?!
