Is sour crop chicken allowed to eat anything that isn’t yogurt water?

[Chickenoreo]

Her crop was full felt like a balloon Monday and been massaging her crop giving her water with apple cider vinegar and yogurt. Today her crop felt smaller and has gotten smaller throughout the day she’s been pooping right after I massage her crop. I caught her eating a pear that was on the floor and I was wondering if it’s fine or I should not let her eat anything besides yogurt and drink water?

I've asked a vet this question a couple of times in the past. I was told that if the sour crop is squishy and not enormous, it's ok to feed easily digestible food. For example mash or scrambled/boiled egg.
