Saving the Berries

I bought some bird netting to put over our raspberry bushes.  I have heard some reports of birds getting caught in them.  I really hope that doesn't happen.  I also only partially covered the bush since it is so huge (well over 7' tall x 5' deep x 20' long).  I'll have to keep an eye on it.  But since we only got about two berries last year, it is worth a try.  If it doesn't work, I'm whacking down the bushes and planting something more tame.
