Sick roosters

[Qualien]

I have a flock of 4 month old crevocuers, mixed with 3 month old ameraucanas. 2 weeks ago all of my flock appeared happy, and healthy. Then in one afternoon one of my roosters started swaying, falling over, and couldn't stand. I suspected snake bite because the symptoms literally appeared in minutes. He was walking and eating normally not 20 min. Before the onset of symptoms. There was no swellings, and no visible injury, so I separated him from the rest of my flock. He had little to no energy for about a week, and had yellow mucous discharge from the eyes ears, mouth, and nose, and heavy breathing with his mouth open. He lost a lot of weight, but started getting better. He still has a lack of coordination, but doesn't fall over, and can now walk, and has normal energy levels, he still has a lot of spittle coming from his mouth, and occasionally pants with his mouth open. Then this morning another of my crevocuer roosters developed the same symptoms. Does anyone know what this could be? How do I keep it from spreading to the rest of my flock? Or should I cull the flock and start over?

Have you added any new birds in recent weeks? That seems like a rather compicated illness. Do you have any pictures of either of the sick birds? It sounds more like a respiratory disease than anything else. If you lose a bird, it would be best to get a necropsy or seek some testing on one of the sick birds to identify the disease. Have you noticed a bad odor on either one’s face? Where are you located? Have you given any medicine? Check the feed for any mold or a funny odor, and if they have access to any compost beds, they shouldn’t. Here is a link for contacting a state vet in your area:

I have not recently added birds to my flock. My most recent addition was the ameraucanas 3 mo. Ago. All of them are behaving fine. I'll see if I can get pics. I did notice a sweet smelling odor on their heads.

There is a Texas lab who will send swabs to collect to test for one or a whole panel of respiratory diseases. Your state vet might be less expensive if they will do it. The most common diseases are infectious bronchitis, mycoplasma (MG,) coryza, and ILT. Some are viruses, while some are bacterial which might respond to certain antibiotics. But they still remain carriers for the disease. Most people cull sick birds or at least close the flock, so to not spread the disease to others. Here is a link for the Texas lab I mentioned:
