Marek's or something else...what should I do

[melbah]

I purchased eggs from a breeder off e-bay that had good reviews. A neighbor took some of the eggs to hatch and only had one hatch. I only had too. Her chick was weak and she asked me to take it and keep it with my other two. It seemed to get stronger but it had a dark bulge on it's underside that wouldn't get better. I thought it looked like internal bleeding. After it was about 4 days old it started looking like it had a hurt foot. Then, after I had it for 5 days my two healthy chicks started getting a wheezing sound in their breathing and sneezing. I looked on line and found Marek's disease. The sick chick seems to fit the symptoms except for it's age. Could a one week old chick be that advanced with Marek's? I culled it right away, but I'm not sure what to do about the two hens. Should I assume it's marek's or could it be something else?

Most of my mature flock has not been vaccinated (now I know to make sure that's done) so I could try one of the remedies on BYC, but will they still be carriers if they get better? I had tried giving the chicks antibiotics and haven't seen an improvement.

These two chicks are especially sweet and attatched to my kids of course!

Thank you for any help...I need to do something quickly for the two remaining chicks if I am going to help them.

I'm thinking this sounds more like pullorum, not Marek's. Here's some information I found online: https://www.ideals.illinois.edu/bitstream/handle/2142/33374/1057724.pdf?sequence=2

I think you will find this is' mycoplasma', it is highly infectious, but quite easy to cure with Tylan antibiotics. It is similar to pnemonia in humans, hence the wheezing lungs.
Quick treatment is always important.
I do hope recovery is speedy.

it is months since I posted my problem, but it was indeed microplasma and the tylan did the trick!
I still have the original 4 chickens I started with six years ago, and the other 4 which makes up my flock are now four and three years old. I get from two to five eggs a day in summer, but only two at present. I am too fond of the old girls to part with them, so they will remain as pets until they drop off the perch.
The oldest are Wellsumers and Bluebells, the youngest Orpingtons and a couple of pure New Hampshire Red bantams which glow like live coals, my favorites!
Henrietta,(Wellsumer) who had the microplasma now only has one eye due to a rat attack, but is still going strong, and laid an egg a couple of weeks ago, the first for months. Thanks for the advise that saved her life.
