A sickness that is not Infectious Laryngotracheitis that causes mouth mucous and bleeding?

Hello again everyone! I have anther chicken question. About 6 days ago I found one of my Silkie hens sneezing in a corner. I had just fed and they tend to engorge themselves, so I thought she was just eating too fast. However when I went to leave I picked her up anyway to inspect cause she was still sneezing. Tha'ts when I noticed she had tons of mucous in her mouth and down the sides of her mouth and it was bloody. She had clear eyes and nostrils but since blood was involved I immediately put her in a crate far away from the other chickens. I gave her some sulfa meds just to be in the safe side and of course, immediately started google-ing. And to my horror the only only disease I can find that causes bloody mucous is Infectious Laryngotracheitis.(ILT)
The next day I went to check on her and she was chirping at me like normal but every few breaths she would gasp alittle. But she ate and drank quite heartily I gave her some more sulfa meds.
By day 3 she had no ill symptoms.
Now it has been 6 days and she is running around squawking to get back with the other chickens. And there is no signs she was every sick.

( I have another little silkie who was also sneezing and had some bubbles in his eyes and he has since developed a thick exudate in his eyes and nares. Its not in his lungs from what I can tell, but he may have what she has, so I put his information here for possible diagnostic purposes.)
Edit: I started him on sulfa meds 3 days ago and he developed the exudate today. so he's getting worse and not better. I think his is environment linked though. We had tons of rain lately and his bedding got wet in the coop. A few other little silkies were sniffling, but I changed the bedding and gave them some hot scrambled eggs and they seem to be doing better.)

Now, here is my question. Has anyone ever dealt with a mild form of ILT and experienced such fast healing as this? After reading other individuals posts, it seems like as soon as they start to bleed, then it is most likely they have the tracheal ulcers already and they are done for. Or is there any other illness that may cause symptoms like this?

I dont have a poulty vet near me so I cant do any blood work, but I dont want to cull my entire flock thinking it is ILT if it is not. I already had a Mycopalsma scare earlier in the year after reading some articles and I sacrificed 2 pullets to have them tested by the state (which is extremely expensive btw when you live in the sticks!). They had all the symptoms but came back negative for anything except a slight e.coli infection.

I dont want to get worked up about internet diagnoses' again and loose more of my flock.

I have a flock of 30 including Ameracaunas, Barred Rocks, New Hampshire Reds, Polish, Black Australorps, SIlver Laced Wyandottes, and my little fluff ball Silkies.

Old thread, but yes, there is a less acute form of the disease which may only make them have a closed eye. Some may not show any symptoms.

Hello.....My Birds have it....I give antibiotics in water...I use Oxy-Tetra-A powder antibiotics in water till symptoms are gone...It does not cure ILT but the other issues...Your Birds are Carriers for life so not recommended to bring in any other Birds unless vaccinated for ILT...Some Birds won't get the bleeding as others will..Each case of it can be mild or terrible...I run heat all winter in order to manage my flock..I lost one Hen that finally could not bounce back...We culled her..

Interesting to read that the OP has gotten testing that was negative for MG, but the symptoms sounded like MG. A close friend and his wife are both microbiologists, and they told me that mycoplasma is very difficult to test and get a positive test on a culture. He actually had MG himself once.

On another subject, many respiratory diseases can occur at the same time or as secondary infections. It would not surprise me to find ILT and MG at the same time. Infectious bronchitis is common at the same time as MG.
