Well, the time has come. We have always let our chickens free range with very little problem. I didn't worry about building a run and figured we always could if we ever needed to. We now need to. Ever since a small pack of neighbor dogs came in August and killed most of my flock we have had dogs prowling around the property. In the last few weeks it has gotten BAD. Like, packs of 8 or 10 dogs at a time. They killed a neighbor's alpaca and lots of neighborhood poultry, They have not gotten any more of mine, but it's only a matter of time with the way things are going. So, I have to build a run for days when I'm not going to be home. I'm looking for suggestions on how to make it dog proof. Like really really dog proof. They have been known to dig under tractors and rip through the chicken wire, so I'm gonna use hardware cloth on the bottom few feet, and also put apron fencing around it. What other suggestions do you have?
