This is my first foray into chickens, into posting on a forum, and I really need some advice. We have a coop and henhouse that our neighbor built for us which we're in the process of modifying as we're learning more about what our 4 week old chicks are going to need. Right now two sides are chainlink, which I understand will not keep raccoons from reaching in. Equally of concern, and a nasty surprise the other day, was how easily one of the chicks walked through the opening. Is there a point when a chicken will be too big to get through those holes. One of the sides is backed by another neighbor's fence which is solid and so I think will keep predators from reaching in...I'm just wondering if a Houdini chicken might get stuck between the chainlink and the solid fence. We are going to buy more chicken wire and hardware cloth (the 1" mesh) to protect them on the other side. Thanks in advance for your experience and advice.
