I did notice your response this morning, it might have been about the same time I was responding.I thought I responded to you late last night.
It looks like Omphalitis, an infection of the navel usually caused by unhygienic hatch conditions or a bacteria entering a yolk that wasn't absorbed enough at hatch. Basically it is an infection of the yolk sack.
The crop will be empty because the chick isn't eating. It is sustaining itself on its yolk and will probably go down hill when it runs out of food and the infection over takes it. The prognosis for this is very, very poor even if a vet were working on it. They can take a long time to die and they suffer a lot. If it starts to go downhill, please just euthanize it. You won't save it. Chicks are really easy to put down--lots of people just take a pair of sharp garden shears or kitchen scissors and just cut the heads off. Don't be alarmed if the chick's headless body moves a lot (remember the saying, running around like a chicken with its head cut off????). Do the right thing by this chick.
I had a chick that probably had this and I allowed it to die and I was NOT happy with myself. I didn't have the courage to do what I needed to do.
We will probably put down the second chick that I'm 99% sure fits the diagnosis on the link. My only hesitation on the Turken is it appears fine. Its running around and seems perfectly healthy. If it starts showing any signs of distress we will euthanize it. This order of chicks has been so disappointing.
