Thanks everyone!
Oh, thank God!!!!!!!! 
e

I know you detailed all this when you did it, but
can you go over EXACTLY what you did??? There are several egg dipping methods, and i will probably be trying this in the future. Also how long you gave the adults the meds before saving eggs? Did the other person you got info from on the meds say whether it would eventually clear an adult bird, if you treated long enough??? I know they work by keeping the bacteria from multiplying, but i don't know if that applies to the bacteria in the damaged lung tissue as well.....
Soooo excited for you!!!!!!!
I will repost it here-
Treat the flock with Denagard, and when the birds get better and the shed level is down, then take the eggs, and dip them in Tylan solution.
Denagard dosages:
Treatment: 16 cc/ml per gallon Give for a full week.
For dipping eggs treatment-
(This was taken from Canada Forum, so things are different in Measurements and temps) I followed everything to the letter...

For my eggs, I placed them in an incubator for 3 hours at 37 degrees. In order to prevent contaminating my hatching incubator with anything that might be on the outside of the untreated eggs I used a second incubator for the initial heating stage. One could probably make a basic heating box with a light bulb/cooler for this if you don't have an extra incubator to dedicate to this procedure. My hatching incubator was disinfected with virkon and set up/prewarmed as you would for normal hatching.
When the 3 hour incubation was almost complete I prepared my Tylan solution. The literature tested between 400 to 1000 ppm concentration - I chose to do 500ppm as I did not see much of a difference in the results from the papers with the increased amount of tylan. This works out to be 500mg of tylan soluble powder per 1 litre of tap water. The tylan solution must be at 5 degrees for the process to work (the antibiotic then travels through the larger pores of the shell and into the egg, aided by the temperature difference between the prewarmed egg and the cold tylan solution). You must add the water to the tylan powder and not the other way around, or the tylan powder will be very difficult to dissolve. I also refrigerated my water prior to mixing and had several trays of ice on hand.
When you are ready, you take the eggs from the 37 degree incubator then put directly into the 5 degree tylan solution. If I saw any dirt/feces on the outside of the eggs, I quickly rinsed the soiled portion under luke warm water prior to putting into the antibiotic solution. The eggs soak in this solution for 30 minutes. I mixed very gently, often using my hands. I also wore latex gloves when handling the eggs and tylan solution.
Once you start adding the warm eggs, the tylan solution increases temperature quite quickly. For my eggs (47 total) I used 2 litres of cold water, 1 litre of crushed ice and 1.5 g of tylan soluble powder. In the future, I would probably also put the egg soaking container in another vessel packed with ice to try to keep the temperature at 5 degrees. Note, that if you add more ice directly to the solution, you also need to add more tylan to keep the concentration in the target range of 400-1000ppm.
After the 30 minutes in the tylan solution, I gently dabbed off excess liquid and placed the cleaned eggs in my hatching incubator as you would normally.
Hopefully I will have a good hatch of myco free chicks in 21 days! Guelph offers blood testing for myco at a very reasonable rate (about $3.00 per sample) so I plan on monitoring my flock in the future for myco. I will basically be maintaining a closed flock from now on, only restocking by way of hatching eggs, and if I do have a bird go off site to a show or something it will either be sold at the show, or return to "freezer camp" and not the general population.
