Mareks or something else?

WHY INTRODUCE HEALTHY CHICKENS INTO A GROUP KNOWING THEY CAN GET ILL FROM YOUR FLOCK . THAT IS SO NOT RIGHT. IF YOU LOVE YOUR CHICKENS WHY MAKE THEM SUFFER. SRY THATS JUST HOW I FEEL . YOU NEED TO EVALUATE YOUR SITUATION .

From my research seems this respiratory and Mareks is very common just weaker strains that most don’t know about are already in thier flock. Since I’ve gotten my hands on tylan so far all my sick ones have recovered and have a great life. So as long as I have multiple roosters I need to have a certain amount of hens. And I thought this was a place to come for help not to be judged and ridiculed. And if you read my other post you would see why I introduced new chickens, so to answer your question that’s already been answered. I need enough hens because I have multiple roosters. Maybe you need to re-evaluate your comment

Also the new chickens I added were from a farmer who only keeps his best looking chickens for chicken shows. So these would of been dinner if I didn’t get them.

But I do plan on after they die off not replacing and sanitizing everything. But I’ve heard this Mareks can live in the soil for years so not sure I can ever get rid of that.

I’ve read so much conflicting stuff on tylan online including here on backyard chickens. Some say orally some say injection, some say both.

But I think tylan only works for respiratory not if this is Mareks.

Should I try another round of antibiotics? I just stoped that last round about 3 days ago. Or should I wait a week?

You are right, Marek's can live on your property for years, it's a disease you likely will have to deal with for a long time.

As for the respiratory illness, most of those don't live in the environment for that long, but sometimes even after culling, cleaning, etc., you could still get more birds that are sick - especially if certain diseases are more common in local flocks. There's no guarantee. http://edis.ifas.ufl.edu/vm011

Most with diseases in their flocks do the best they can to manage symptoms like you have been doing.
Marek's does complicate things and it's a virus so antibiotics do not help with it's symptoms. Supportive care (for Marek's) includes vitamin therapy (B-Complex), keeping stress levels low, see that the bird is eating/drinking well, stay on top of parasites like worms and lice/mites, etc.

Having respiratory disease in addition to Marek's complicates things for you. I can't imagine what that's like. If the birds do respond to antibiotic treatment and you mentioned bubbles in the eyes, then most likely you are dealing with Mycoplasma - but really the only way to know for sure would be with testing.
Managing symptoms is usually what most do if they have MG in their flock as well. Denagard is often used to help with symptoms and given to all the birds for 3-5 days each month - this may be something you want to look into. Denagard will only treat MG.

As for Tylan50 - yes, there is a lot of dosing information out their and it can be quite confusing. I try to go by something like Plumb's vet drug manual whenever possible. So....
The dosing information I have is from Plumb's Vet Drug Manual - the dosage for Tylan (Tylosin) is 10-40mg/kg given 3 times a day for 5 days.

I would go with a mid-range dosage of 25mg/kg - that translates to 0.227 mg per pound of weight. Personally I would round up to 0.25mg per pound of weight so it's easier to calculate (you have plenty of wiggle room on dosing - remember we are looking at mid-range on dosing here).
After all that mess of me running my mouth - this is what I would give - 0.25mg per pound of weight orally 3 times a day for 5 days.

IF you were only giving an injection once a day and this girl is very sick with the respiratory symptoms - then yes, I believe if she were mine I would give another round of Tylan (orally, 3 times a day for 5 days).

Now...another thing, just in case you are not aware. A LOT of antibiotics are hard to find. Tylan50 and 200 have been taken off the shelves it seems. Tylosin (which is Tylan) powder can be used but you would need to order it. Lots of places have short stock or no stock, you have to look daily (hourly?) It would be a very good idea to go ahead and order yourself some Tylosin (powder) to keep on hand since you do seem to have an ongoing problem here.

I'm very sorry that you are dealing with all this. Keep us posted on how she's doing.

Thanks so much for the helpful info. Wow I didn’t know they took tylan off the shelves. Where would I order that powder from? I used to get my tylan 50 off amazon or tractor supply.

2 Places I know of - both places seem to sell out pretty quick. It's been within the last few months that Tylan was taken off the shelves.

Editing to add - if birds are really sick, they may not drink enough of the medicated water on their own, so you may need to syringe the water into them every few hours.
