Banty seems dizzy, feathers are puffed up, sitting by herself

[lndlubr]

I have a little banty that is about 10 months old. When I let everyone out of the coop this morning she came out, but had her tail down. I approached her and she perked it up and kept on walking with the other chickens. I went out to check on her a few minutes ago and she was laying in the corner of the run alone, still puffed up, not interested in scratch. When I bent down to pick her up she tried to get up and walk away, but seemed a little of balance. (She usually runs from me, she doesn't like to be handled). I carried her out and was going to get a crate ready to separate her from the rest and she pooped on my shoe. It was white, with a little bit of normal green color, but very runny. She seemed fine last night and none of the others are acting this way so far. They are all contained in a run, they do not free-range, but we do have some that do free-range that share the run for short times with her. We're still fairly new to chicken illnesses...what should I do first? I have some things on hand I can give her - Corid, Tylosin, Vet Rx, vitamins, and maybe more that I'm not thinking of. Currently she is in a crate on her own, I'm about to go get water and food for her (she's only been in it long enough for me to write this).

Do you mean one hen is behaving lethargically or is it two? That detail could be important.

Is this little girl laying? If so, when was her last egg?

My apologies, it was a typo. She's the only one doing this. I offered her food and water. She did drink. (Yay!)
She does lay eggs, she lays in the same box as her sister so I honestly can't say for certain when her last one was, they seem to alternate days. That being saud, we have been getting green banty eggs everyday. I tried to feel her abdomen to see if I felt an egg and I don't think I do. But I've never tried to feel for an egg before so maybe I don't know what I'm feeling for.
She is in the crate kind of laying on her side. She has her beak open and I can definitely see her breathing. She is alert though.

She may be egg bound or have some other material obstructing her oviduct. You aren't always able to feel an egg.

Give her a calcium tablet immediately. If she is blocked, this can produce strong contractions to push the obstruction out. Place the whole tablet directly into her beak.

Like calcium for people?
