We just scare the non-poisonous snakes back into the woods, we don't have baby chicks to worry about. I am only getting 4 eggs a day, and we pick them up each day, so if I loose 1 or 2 it would be ok. We usually see black snakes, racer snakes, rat snakes, but the copperhead that bit my dog had to die. She lived, but had a fat lip for almost 2 weeks.
