Hmm, doesn't sound good. I'm not much help on sickly chickens.Yes on Corid since yesterday afternoon.
Tried her on some eggs just now and she was not interested at all.
Crop is small.
As of yesterday her poop looked normal. But, since I got a hold of her this morning she has not pooped at all. I have a dropper with the corid solution in it that I have been giving her little drops of and she kind of drinks but it certainly is not much. I admit to being quite worried now!
She is standing now, like in the photo, and peeping gently.
If you really want to get the corid down her, you may have to use a syringe or dropper and get it directly into her crop using this method:
