In our yard we have this one small section of wild. there is brambles and all kinds of stuff and I think the chickens would have a blast foraging in there. But we have one concern. We have a little snake that lives there... It is a garter snake, so is not poisonous, but I was wondering if it would threaten our hens. They are currently around 4-5 weeks old, so will not be free ranging yett but I am not sure weather to be worried or not.
