I have also tried the powdered antibiotics from the feed store. The one with the animals on it. I found out about the tylon but it hasn't made a difference. Any other suggestions. 1 year old mix breed hen. Finished molting when she developed her symptoms. Which was a swollen eye. And her head is also swollen looks to be sinuses. She is still eating fine and is fiesty. The other birds have not shown anything.she is on saw horses in a dog kennel. I had my birds tested for MG. And the other basic tests for npip.this was the only way to test for the MG. Haven't had the results yet. I have no other place to put her as I purchased chick's 3-4 months ago and was going to put them in with the others however this one is sick so they are in the barn.
