Is blackhead a problem everywhere? I had heard that it is not a problem in all parts of the US. I live in northern Minnesota and my place has had chickens on it only for three years. The barn I will be brooding my turkeys has not had chickens in it for two years now. How long can it (I am not even sure what 'it' is) live in the soil? I am planning on Bourbon Reds, Thanks in advance!
