I have an Americana that is roughly 6 months old. The other evening I noticed her eyes were runny and bubbling and that she was kind of "gurgling." I immediately separated her from the rest of the flock while trying to identify what it was. Her symptoms seemed to match that of MG. It was late already so nowhere was open for me to go get the recommended meds. I went to check on her the next morning and she seemed to have cleared up for the most part. I'm confused because, although from my research it seems chickens can bounce back from MG, it didn't sound like something that would clear that fast. I'm still keeping her in QT and have been putting Poultry RX in her water and on her beak area every night. I'm a marine biologist and normally with fish we tend to shy away from treating things when a diagnosis is not certain as the wrong med can cause more stress. I know this is a chicken, but it still seems logical to me not to pump a med into something on a hunch. Especially if the animal is doing better. She is eating and drinking just fine. She doesn't seem lethargic. It's been 3 days and now her sister (literally the other Americana chick I bought with her) now is showing the same symptoms but less severe. So I'm thinking maybe they were carriers from the get go. Thus far other than the other Americana no one else in my flock seems to be having any issues. As a note it was literally raining for weeks on end where I am at in Texas. Then the mosquito's were just all out terrible until a cold snap came. I know all these combined have just been the perfect storm of stressors. The mosquito's have also caused a minor outbreak of fowl pox but from understanding this should just clear up on it's own. So I'm sure all this stress could have just caused a few to have weakened immune systems. I'm kind of bummed that it could be MG as I wanted to kind of play around with breeding but that means I can no longer sell any chicks. I just don't have it in me to cull a flock. I'm far too attached unfortunately. I also realize the only for sure way of knowing is to take her to a vet which I plan on doing after the holiday. But I just wanted to get some others opinions. It was my understanding that Deneguard was needed to usually help the chicken get over it. So my question is: Is this normal for MG to clear up overnight or is it maybe something less severe?
