Hello Birdiefluff, Happy to have a fellow NC chicken enthusiast. I am so sorry you are having an issue with Blackhead disease. I hope that you are able to get that under control.
Sorry you are dealing with Blackhead. It can be difficult to treat. It may have come from wild birds? It's hard to see your birds sick. Good luck and welcome to our roost!
Welcome to backyard chickens so glad you joined the flock!
Feel free to ask us questions and answer questions! Make yourself at home!
Hope you enjoy this site as much as we all do!!!!!
Here is an article that I am sure you have read. Killing the roundworms is one part of the battle but unfortunately it doesn't solve the other half. Truly sorry your flock has been hit with this issue.
