Is the G-tubing 1.2cm? It shouldn't be any larger or it wouldn't fit well inside a chicken's throat. Do you have an oral syringe that will fit snugly inside the tubing? If not a good fit, it will make an awful mess.
Let me know when you get the tubing and syringe gathered up. This chicken will die if she isn't fed food and water very soon.
There is very likely other more serious infectious agents at work in your flock. I do not agree that quarantining at this point will accomplish anything. Avian viruses, which appear likely, are so contagious, all your flock is already infected if these viruses are present.
My opinion is that this chicken's life needs to be saved before you do anything else. Have you give the vitamin E yet? This needs to be started immediately. If you do not already have Poultry Nutri-drench on hand, you need to stop at the feed store and pick up some. This will help save the hen's life by getting nutrients into her system as quickly as possible.
