Igor? Good name. I want to name another barred rock Geisla. I have to look up the correct spelling. Gilda and Geisla. Anyway, worms. We had/have the typical sand of Sherburne county and I have amended it in the garden, plus all the leaves and branches on the river bank make it more compost than sand, and hence, earth worms. Which are good for the plants but bad for turkeys. Since I do not raise turkeys I am not too worried and I am not selling chickens so I am not worried about spreading this if my chickies have it - but does it affect their meat?
As far as I know it does not affect the meat, eggs or anything on the chickens. I think it is like brain worms in moose, deer carry it with no effect and it kills moose.
