Protection from flying predators

[jrudolph305]

At out last home we had a run that was out in the open and I put bird netting over the top. Where we live now I have an area that has trees and brush. I would like to put a 25' X 25' run in but can't really cover it. Will flying daytime predators be a problem? Also if I have about 20 hens would 1 rooster be enough?

I'd want at least 2 roosters with that many hens.
Whether or not hawks will be a problem is nearly impossible to predict.
Many people have uncovered runs and never lose a bird

I find hawks usually take young chickens that don't have a mother hen or a rooster to protect them. I have never lost full grown birds to flying predators.
