Thank you everybody, this community really rallies and it's amazing.Hi
I'm sorry your hen is not well and you feel let down (and fleeced) by the veterinary service. Can't say I blame you!
Is she able to poop at all. If she can pass faeces then I would not be in too much of a hurry to take action. The threat to her health is from being unable to eliminate waste. Usually, when they are egg bound, the egg is pretty much there inside the vent blocking the intestines. If it is further up the oviduct and you didn't feel it during an internal exam, I'm wondering if she really is egg bound. Do you have the x-rays and if so, can you post them so that we can see what the vet has seen. I'm concerned that this may be salpingitis and not just straightforward egg binding. That would explain the misshapen egg. It could of course just be a soft shelled/shell less egg that is proving very hard to expel. Could you see a very clearly defined egg on the xray? If you haven't got the xray, you might want to ask for it.....since it has cost you so much money and is of no use to the vet anymore.
If she is unable to pass waste, her digestive tract and crop will start to get slow and unfortunately that will slow ingestion of calcium and any oral antibiotics. A shot of calcium might have been helpful and perhaps IM antibiotics
