I did withhold food until her crop went down.
She is better, more alert, interested in her regular food but not so much with the yogurt/etc. I leave at 4 am tomorrow so I put her in the brooder in the big coop - turned on the brinsea brooder in case she got chilled, got her food and water set up,.....when the two sibling chicks came in the coop for the night, she saw them and started distress calling. THey called back, screeching - oh the commotion - I finally let her siblings in the brooder with her.
When I leave, I will take the sibling chicks out, but I think I will leave her in for another day.
She is still a little puffed out, but her posture has improved. I've had false hopes before, though....
I found that the 2nd time I put her in a crate that waiting the five days before having real food worked the best to clear her crop. The first 2 times I only had her on it for a couple days.,
