I just finished cleaning out an old pheasent run for my chickens that have not arrived yet, and I have kind of a strange question... I want to plant some kind of fast-growing vine (the pen is covered top-to-bottom in chicken wire) to shelter them from afternoon sun. I was thinking along the lines of morning glories (except these are a no-go as they are poisones to chickens).... they grow fast, are very light (I don't want it to pull down my chicken wire!) and provide coverage. Anyone have any ideas on a similar vine that is not harmful to chickens? I live in So Cal, zone 8-9 (I cant remember which) I would like to get something planted soon, so it will have time to establish before the chickens are old enough to go outside.
