I have a 30 week old Brabanter Rooster. He has been generally healthy until last night. I noticed when I went into the coop to close up for the evening, that he was roosting on the floor next to the hens and not up on the bars as he typically does. This morning, he was still there but with his head in the corner. I picked him up and brought him into the house to confine him. This morning I took him to the vet. She is not familiar with poultry but saw us anyways. She told me to go to the Veterinary school near us for their opinion - they have told us that it is $100 to get in the door and will likely end up costing us over $600 if they do any testing or treatment. So, i am looking for some help/advice from the brains here. This is what I have for info at this point: 1. Free ranges 2. Has had a Corid treatment in the last 30 days 3. 16 hens and 1 rooster 3a. there are no other birds who appear to be affected. 4. There is no nasal discharge 5. His comb is red 6. He is alert, eating, drinking and crowing 7. His eyes are clear and his pupils are reactive 8. We have not had any additions to our flock. 8a. A couple weeks ago we had a juvenile bird die with totally different set of symptoms. 9. There is no sign of trauma, no sign of injury. 10. He has been vaccinated for Merek's. 11. He is doing a bit of open mouth breathing but it seems to coincide with him trying to walk or move around. or being stressed by the car ride to the vet's. 12. No signs of lice or mite infestation. Any thoughts or advice would be appreciated. I can upload a video or images if it would be helpful. thanks in advance!!
