This morning we lost our lavender orphington. She started acting funny a few days ago and we finally got a hold of our chicken guy this morning. He told us to go get Tylan and bring it to him with the bird. When we got there, it was too late and we lost her. We were told it was Bronchitis and he showed us puss that was on her eye. Now we are wondering if the rest of our flock has been infected. Our birds are pretty wild and do not like to be touched so it's hard to get a close look at them. I did notice one standing alone and not eating when I got home. I called our chicken man and he said to give her the Tylan as well. Does anyone else have experience with this sickness? Any advice on how to notice symptoms before it's too late? Any help would be great!
