Sooooo glad you remembered the olive oil! I knew she was getting constipated! That can kill a chick, too, although it's a lot slower and very painful.
I'm as overjoyed as Blooie to hear our little patient is improving, by what sounds like, leaps and bounds!
The amount of olive oil required will depend on how large she is. Constipation can happen any time, although it seems to happen with week olds more than any. You really can't overdose her, so don't worry about it. You just want to make sure you give enough to get the job done. I've used olive oil in both ends of a chicken, sometimes at the same time when I'm not real sure what's wrong. Sort of like castor oil was given in the olden days as a catchall remedy. And you can give that to chickens, too.
I bet she might eat the tofu, too, if you offered it to her again. Here's a trick. Offer it to all of them together. She will probably eat some if the others are eating it.
Did you manage to locate that Nutri-drench?
