Chickens developing Slow Growing Disease/Sickeness and Dieing

[Breakofday316]

Started the corks on Saturday. Hopefully this is what has been going on.

Alright Everyone! It is BACK AGAIN. Another chicken developed symptoms and is declining quickly, stopped eating and drinking. Uneasy on legs, crouches down on elbows most of the time. Closing eyes even when i am talking to her. Poops are runny. HELP!!!

She is a Golden Cuckoo Maron almost laying age. She was fine, then one day she was in the corner all puffed up. I separated her and started immune boosters: poly-vi-sol, vit e, selenium, and Vet RX mixed with water and mixed with her softened food. She drank some of the water, however when I went to pick her up she started spewing it. I then thought she possibly has Sour Crop. Tipped her over 2 times, more liquid came gushing out. Since last night she has not drank or eating anything. If she doesn't eat or drink I know she will continue to decline.

Does she need ATB? I have Tylan 50 inject-able, would rather give orally.

Any suggestions will help. Her name is Charm.

Did you ever get any results from the necropsy they did on your last hen that died? I had a young hen around 8-10 weeks randomly up and die today with very similar symptoms that progressed rapidly over a matter of hours before she died. I am at a loss and all my other hens seem completely fine :-/ I'm so worried it's something that will spread, but she has no symptoms till today...very frustrating!

Charm surprised me & did not die! Although I still have an issue on my hands. Talked to vet and symptoms point to marek's he stated. When another dies, I need to send in and confirm. Vet says what my flock has seems slow growing, taking months to show symptoms. Symptoms start around 4-5 months of age. My birds are not vaccinated.

UPDATE:
I had three silkies die recently. Shipped them off to get necropsy because everything pointed to Marek's Virus. Thank the Lord that I finally got some results: COCCIDIOSIS- Eimeria Necatirx.Treatable with Amprolioum and preventable for future up bringing. So thankful. Wish I would have done this sooner, 11 birds die since November 2015 (7 month period). Effected 26% of my flock. Fingers crossed this will take care of all the issues I have been experiencing.
