HELP! my chicken has diahrrea, bad breath, runny beak, drool

[pikachupacabra]

About a week and a half ago I bought a 4 month Old English Bantam hen. She has had very liquidy poos a couple of times since she came home, but since she was behaving normally otherwise I figured that it was probably from eating things she wasn't used to.
Also, after the runny poos she has had normal poos the rest of the day.

Anyway, yesterday I noticed that she was just sitting with her eyes closed, which didn't seem normal (I don't know, do chickens take naps?), and I have been watching her closely since then. Last night she seemed fine, and fine this morning, healthy appetite, etc.
But this afternoon she was sitting on the ground with her eyes closed again, and this time she also keeps opening and closing her beak, in a motion that looks kind of like someone smacking their lips.

I pulled her out of the coop, to get her away from my other chickens, and gave her a closer inspection. Here's what I noticed:
She has very stinky breath
She keeps breathing through her mouth
Her beak is runny
She sneezed and blew bubbles out of her beak
She feels like she has a fever (what is a normal chicken temp.?)
She looks a little flushed behind her ears
She still has diahrrea, and there is either blood or carrots in it...not sure which, she had some carrots this morning
She is not drinking water, although she still wants food, however when she tries to eat she drools and then flings nasty, smelly chicken drool in every direction...

Her condition seems to be degrading as time passes.

I have her in a pet carrier with fresh water and some of her layer pellets mixed with yogurt....
This is the first time I've ever had chickens and I don't know what I can do for her...
If she dies, of course I will be sad, but I'm really scared that ALL my chickens are doomed...

I tried searching for help before posting, but everything I read either left me with more questions, or didn't totally fit my situation, now it has been a long enough day that I am starting to panic...

Someone please tell me what this could be, and what to do...

Thanx

Hi
I know this is an old post, but were there any replies? I just came across it in a google search to try and figure what's up with my girls who have exactly the same symptoms. The vet didnt know what it was but prescribed antibiotics (not effective) and the closest I found online and from the poultry forum was mycoplasma. I have lost 3 hens to the same illness over the past couple of months and one of my remaining two now looks as though she is coming down with the same thing. A different vet said that mycoplasma is rare in backyard garden pets - more a problem in young birds in intensive units. My hens are 8 or 9 years old (buff orpingtons), so a bit past it, but they were happy and healthy and still laying a few eggs without any previous illness until this. I am also really concerned that it might pass to my two 2 year old ducks who they live with in our garden.
If anyone has any suggestions I would be very grateful....
Many thanks
