Oh wow, so sorry Farmerboy.
I don't know what the solution is because I have never heard of this before. Do you know how it got into your flock?
I am so glad I have already decided to have a closed flock if these are the kinds of things you can end up bringing home. I worry enough about anything wild birds may transmit. I chase them out of the yard while I wait to build my covered run.
