I love using chain link kennels for our birds. We have both large and small predators, and the chain link keeps out the bears and mtn. lions, and I add hardware cloth around the bottom for anything that can squeeze through or reach through. I have mostly bantams, and when they were younger they could walk right through chain link. Weasels are the only thing that can climb up and squeeze through now, but my girls are locked in the hen house at night. I haven't had a problem yet. Also have wired the top. Couldn't use netting because a bear would have no problems getting through. Although a bear could rip through almost anything. They get into neighbors campers and tear through walls into people's houses. Have to hope they'll be happy with the neighbor's trash and leave the chickies alone.
