What would be an ideal material to use as the cover? It has to be breathable as it gets really hot here in the summers, maybe like a shade covering though. I don't really want to put hard wire or chicken wire up unless it's my only option.
The hawk hasn't bothered the chickens yet but was in the tree over the neighbors yard and that was apparently close enough to worry the girls. They all went and sat under the bamboo till they felt it was safe
