This is a followup to my chickens in the backyard post. Our chickens had such a good time yesterday, that my Dad let them out again yesterday and today. I'm happy, because it provides more enrichment for them that I can provide in their run. I did have some questions about chicken proofing our backyard though. One is that they were digging up the moss (which is so tough, that I can't imagine it going down). Is that a potential crop hazard, or can I trust them to leave it alone? Also, my Dad did say that we have a plant that is on the poisonous to chickens list, but that he thought it was well hidden in the back where they wound find it. What would be a good way (may some wire around it) to keep them from getting to the plant in question? Also, they did get caught in a downpour and got pretty wet. Will they learn to go back to their run for shelter, or would it be a good idea to put a shelter of some kine up until our rainy season ends?
