My routine is to throw my compost into my vegetable garden at the end of the growing season, work it in really well and let it sit over the winter. This year I figured I'd let the chickens work it in. My problem is that I have not been discerning about what I put in the compost. Primarily concerning cuttings from toxic plants. They are already partially broken down and will continue to breakdown until fall. Do you think I need to worry about the chickens getting sick?
