Strange Disease

[AMilkyWay]

Hello all I have 135 Hyline Brown (their name down here in Honduras) chickens all between 18 and 25 weeks in two locations. Three weeks ago I had one girl show up with a respitory infection and was treated and recovered within four days. I noticed she stopped feeding again on day five in the afternoon and removed her on day six. She had no breathing trouble and her only symptom was what appeared to be a dialated eye and holding one leg up, being lethargic. Morning of day seven I found her dead. The last two weeks I saw no other animals with the same symptoms then two days ago I noticed one more girl with the same behavior. She had a dialated eye, holding one leg up, and lethargic. I removed her and within 24 hours she passed. On the second girl I did a necro and liver, heart, and other internal organs looked good from what I can tell, only a swollen gall bladder. Any ideas on what I am facing? My first thoughts were ocular mareks or LL but these girls are all young and it takes them out so quickly. Also my necro wasn't the most proffesionally done. I have more pics but will only share if requested.

Mareks tends to cause lameness and paralysis in one leg, where one leg may be forward and one under or backward. Ocular Mareks which is more rare and the eye color may be faded with the pupil appearing irregular and small. Respiratory diseases can cause air sacculitis and eye pupils sometimes can appear cloudy and dilated. With a necropsy, it helps to see the liver clearly, along with intestines and other organs to look for the tiny cysts. Sorry for your loss. Have a look at this link from Cornell to view pictures of clinical signs and gross lesions of Mareks signs:

Hello, thank you for the reply. If not Mareks what would you think it could be? If its respitory the girls didnt show any breathing difficulty prior to passing and I would think it is viral due to the first passing after seeming to recover from antibiotics. I live in Honduras and dont have access to vets or labs so any advice is much appriciated. The chickens I have are used to feed children at a home and also a project in a rural community. Sadly I dont have better pics of the liver due to getting my hands dirty but from what I can tell it looked clean along with intestines.
