Here is my story on the netting. I have the "cheap stuff" from Lowes. I could not afford the other. I had hawk problems last winter. I also had the run rebuilt in the fall and expanded and to make a long story short never got around to putting the netting on. OK,,,now the netting has to go on as the girls have to be put in lockdown until the hawk moves on to other places. My daughter and I ran to Lowe's and put it up as best we could, it was freezing out and getting dark. We did the best we could but it was not good enough as we left a couple of gaps and figured it would be ok until we had more time on the weekend. I came home from work the next day to find the hawk in the pen. He did not in any way "rip" the netting. Actually there was no damage to the netting at all. It was completey my fault for waiting till the last minute and rushing and not doing it right in the first place.. Once the netting was done correctly that was the end of that. No more hawk and I have never had another problem with it. It was economical and has served it purpose. Sometimes you don't have to spend alot of money to get the same results as spending more. Just my story on netting.
