I'd like to plant vining flowers and veggies around my chicken run, which has a plastic mesh fence, perfect for the vines to crawl up. They would add some beauty to the run. But I have read that flowering sweet peas are poisonous. Do you think the chickens would eat sweet pea vines and get sick? I'm also considering edible peas, but would they destroy the vines before the peas could form, even if the vines are planted on the side of the fence that is outside their run? I'm thinking once the vines start twining around the mesh, the chickens might eat them? I'm also considering morning glories, but once again they are considered poisonous? I thought I saw my chooks munch on bindweed last summer with no ill effects, but I guess it's a different type of morning glory? I have read that chickens pretty much stay away from plants that are bad for them. What do you think? It's about time to get the sweet peas/edible peas in the ground.
