Hi all, So, my boyfriend and I went to Lowe's today to get metal stakes and poultry fencing to build a chicken run. The soil is super rocky here in NJ, so we could only drive the metal stakes in about 2-3" before they hit a rock. In the end, all the stakes toppled down. What are your tips for beginners trying to build a run? Particularly, what's the best thing to do about stakes in rocky soil? Also, has anybody used this "Electric Net" poultry fencing? Is it any good? It makes me a little nervous because it has no roof to protect from hawks (we have a lot of hawks in our area). Oh also, I have 30 chickens, so the run would need to be at least 15' by 15' or so.
