I have 2 BBB's that are being raised alongside my laying hens, as well as a few CX stragglers. Found out about blackhead after I had purchased them, so that is my fault. I checked with the local feed stores, and they say nobody in our county has reported issues with it. I'm sure that doesn't mean that we are immune to it, as it can always be brought into an area. I was wondering when you would usually see it? My two turkeys are 8 weeks old, and are progressing nicely, with no signs of illness. They also free range with my other birds when I let them all out.
