Mysterious disease...what on earth is it, and how do I cure it??

I noticed this morning that one of my roosters was having trouble walking out of the coop. I picked him up, and found that both of his eyes were swollen and infected. He was shivering, and his breathing was raspy. I've got him isolated, with electrolytes and some Duramycin in his water, simply because that's all I know to give him right now.

Last fall, the same symptoms wiped out almost my entire flock. I never could figure out for sure what this disease was, but I really don't want to deal with it again. So, here's a list of the symptoms that I saw last fall, and this morning:

Shivering

Raspy, quick breathing

Infected, foamy, slightly swollen eyes

Runny nose

...I can't remember if there was a significant poop change...I'll check here in a bit.

'Sulking' in the corner...hiding

Skin going pale, comb and wattles turning slightly blue/purple...from lack of air I suppose.

Death

If I find anymore symptoms, I'll post them. Also, I tried to get a picture of his eyes. My camera didn't focus very well, but I'll post it anyway:

Yeah, the camera focused on the tuft of feathers closer to the lense. : /

If anyone has any ideas on what this disease is and/or how to treat it, I'd love to hear your opinions!

Thanks in advance!

Thank you so much! Both links were extremely helpful! I feel so much better now that I know what it is. :)

I'll be going out to the feed mill later this afternoon, and I'll pick up some Tylan or Baytrill, if they have it. Will Tylan/Baytrill treat both MG and Infectious Coryza? I'm pretty sure what I have is MG, but still...to be on the safe side, I'd like to get something that'll cure both.

Thanks again!

I'm not smelling much from him....either way, I've got some Tylan- the water soluble kind. Should I go ahead and medicate my whole flock? Also, I can't give this stuff to my chicks can I? It would be too much for them, right?

Mmkay, thanks for the advice! I think I'll go ahead and medicate the whole flock then. The chicks have not been exposed that I know of. Still, I might just medicate them too. What about my 5 day old chicks? Should I use half a dose for them?

I did consider doing the injection, but he's not the worst case I've had- compared to the ones I had last fall. I'm dreading clean-up after all of this. O.O

Again, thank you everyone for all of the advice!
