Thank you for your help. I took her to the vet and after an x-ray, they said it is egg yolk perintonitits...however they didnt prescribe antibiotics!!!! Can you tell me if I should use penicillin, tylon, or liquamycin??? Going to TSC now...

I'm sorry the news it not good.
I am glad you were able to go to the vet and get a clearer idea of what is going on with your sweet girl.
Antibiotics might help with EYP, you can try. Personally I would use Baytril or Amoxicillin - you won't find either at
TSC. You would need to order those.
If ordering is not possible, then among the 3 choices you posted, I would use the Tylan50.
That's my personal opinion - someone else may have a better suggestion.
Did you happen to get a copy of the xray and do you mind sharing it so we can learn?
For a hen that is having reproductive problems, I would also give her vitamins once a week. Again, personal preference is Poultry Cell. I direct dose at 1cc per 3lbs of weight.
Check her crop regularly to make sure it's empty in the mornings. When a hen has a reproductive disorder, that can cause internal swelling, which in turn can restrict the digestive process - this slows crop function. It all goes together. I monitor the crop closely with any of my gals that have repro problems - if I note anything, I begin a mild treatment for slow crop to help keep things moving. You don't want to deal with sour crop. I usually do fine with giving a little coconut oil (freeze it, break into chunks, they love coconut oil), massage the crop gently a few times a day. I don't limit food unless I have to. Most of the time they will drink very well on their own. I do offer wet feed as well.
I hope you can pet your girl along for a while with supportive care. Keep me posted.
