I'm sorry to say Marek's gets my vote too.
The reason is that she is at an age when they are most vulnerable, she is showing fairly classic neurological symptoms. Respiratory problems are common with Marek's.... either secondary infections due to a suppressed immune system or the lungs being a relatively common site for the development of the tumours. I have had birds with Marek's recover as rapidly as they got sick, others decline over a period of weeks and either die or be assisted and others that held their own and eventually made enough of a recovery after months of supportive care, to rejoin the flock and even free range and lay eggs. And some that died suddenly with almost no warning. It is a strange disease with no hard and fast rules. Coccidiosis is another secondary infection which can result from Marek's.
My experience is to support the immune and digestive system. Good quality poultry supplement and good quality food (including animal/fish protein eggs etc) and probiotics/fermented feed to ensure the bird is able to get maximum benefit from their food. Sunshine, grass and the company of other chickens (in a safe environment where bullying cannot occur) are the other factors that seemed to make a big difference but not easily arranged... not least because you cannot get sunshine on prescription.... especially here in the UK!
If you have been giving antibiotics for several days now (4 days of Duramycin and 3 days of Tylan 50) with no obvious benefit and no obvious sign of infection, then I would discontinue their use because the health of the gut is more important in my opinion with this disease, than using something that is known to compromise the digestive system with no obvious symptom to treat or benefit so far from using it.
