We have 7 chicks right now that will move to the coop in about a month. We plan/planned to free range as much as possible on our 10 acres, but I am worried about them eating something harmful to them. I have just planted lily of the valley plants as well as a clematis and both are said to be toxic to chickens. Are these things I need to remove, or do chickens naturally avoid things harmful to them? They aren't in the direct vicinity of the coop, but are definitely accessible. We have about 5 acres of woods and another 5 of lawn/field.
