We currently use 50m electric nets for our hens and so far have not had a predator issue, other than rats. But, it is a lot of work to keep it all maintained. In the summer you are constantly trying to keep the grass down and in the winter it's a matter of stopping the wind blowing it down all the time. I think it's a good solution if you want to keep moving birds but we are looking at some more permanent pens now for small breeding flocks. Another issue we get is crows and magpies stealing eggs.
So, the idea I have is to use 6ft post and wire. Tornado poultry fencing at the bottom with the base let out to stop digging. This will be about 4ft high. Then for the top 2 feet, multiple strands of strong electric steel wire. Also 2 strands of electric on the outside of the posts at 1 and 2 foot. On top of the run, bird netting to stop egg thieves but big enough not to catch too many leaves.
Anyone have a similar setup and have any tips?
