What kind of bedding is the chick on? Shavings? Fine shavings or big flakes? You want big flakes, not the fine shavings which they tend to eat and can cause blocked crops and gizzards. Don't want hay either. That's just as bad.
Crop does look big. Did it go down in the morning? If it didn't, you may have to start gently massaging the crop several times a day to try to get whatever the chick ate to move past the crop. Do the chicks have any chick sized grit available to them? How many chicks do you have and are there enough feeders to accomodate the number? Sometimes chicks wlll eat what they find on the floor if feeders are overcrowded.
But, yes, you could have a crop bound or gizzard impactation going on there and the chick is just starved and dying. Try massaging and get a vit/mineral supplement in the water and try giving the chick some nutrition with the mixed water. Use an eyedropper or small syringe and see if you can get it to take some drops of water. You are going to have to do that often. Hopefully you can get the mass to go down and hopefully it's gizzard isn't impacted. If the bird is pooping, then stuff is passing through and there may be some chance of fixing this. Meantime, check your bedding, feeders and chick grit to prevent this from happening to others.
