For what it's worth...I recently had some kind of respiratory infection go through the flock. Symptoms were: crusty around eyes, ears, & nostrils. On some, the discharge was stinky, on others, not. The symptoms varied in range & intensity from chicken to chicken. I checked the internet & a couple of forums, trying for a diagnosis, but those varied too. So, here's what I did. I ordered injectible Tylan to have on hand in case symptoms got really serious. I also got some VetRx (I think it's organic but not sure), some eye drops called "1 drop, 1 eye, 1 time), some Neosporin, saline solution, lots of fruit-flavored yogurt, & a bunch of meal worms. If it's beginning to sound like I'm planning some hoodoo voodoo witchy stuff, you're not too far off.
First, I tried isolating the sick birds, but it was spreading too fast, so I just started treating.
If there were any symptoms at all, I washed around their eyes, got off what crust I could from eyes, nostrils, & ears, then rubbed Neosporin around the eyes. Everyone got dosed with the eye-drops & the VetRx. I continued with everything but the eye-drops for the next few days until I started seeing some improvement.
For a few that were sick enough to quit eating, I isolated them & started feeding them all the yogurt they would eat, along with bunches of meal worms. They couldn't resist the goodies & recovered their appetites very quickly. NOTE: for some reason, when chickens eat the mealies, their poo smells like a cesspool. So don't be alarmed if you walk in the pen & are blown away by the smell.
Everyone recovered from whatever they had & I never did have to use the Tylan, but I'm glad I have it on hand in case something else comes along. I've also stocked up on the VetRx & will make sure I have all my "sick bird supplies" on hand in case something else comes along.
Good luck with your chick. I'll be thinking good thoughts for her recovery.
