Well, pic #1 looks to me like solids are collecting at the bottom of the crop and not passing through .. not good. Pic #2 appears to have been taken from above the bird and looking down on the back and the little "pockets" above the shoulder joints .. definitely air filled. Hard to say what's really going on here, but my guess is that the crop is impacted at the bottom and food is not moving out.
You are going to get lots of opinions and suggestions, so use your head and try to match what is being said to what you are actually seeing with this little bird.
My suggestion is to tube a small bit of warm water with a couple of drops of vegetable oil in it and then massage the crop to break up any masses and see if the crop empties.
If it does not empty, then we are into more serious territory. You can't keep putting "stuff" in if nothing is going out.
Please carefully read whatever may be posted in this thread, and let us know what action you may be taking.
EDIT: You may also need to try to gently "burp" this bird by gently pressing the air out of the crop with your fingers. I apologize for not just calling you in the first place, but I think it's getting too late at night to do that now.
