Overhanging gourd vines?

[Pent]

I came across the interesting information that gourd leaves, because they are so strong smelling and bad tasting, are rarely eaten by animals such as domestic rabbits, among other creatures, and thought it might be a good plant to grow up the wire of a chicken run. I can't seem to find specific information on gourd leaves and vines, as they relate to chickens, however. Has anyone tried to feed their chickens gourd vines? I wasn't sure where to put this question, as it plays a part in my coop design, but is also kind of a food question.
My question is twofold; will they eat them, and will it harm them if they do? I'm talking about hard gourds, the kind used to make bottles and birdhouses.

I have not seen any books, people, or websites hold up any red flags for gourd vines being toxic. What you can do is look up toxic plants to chickens and see what that bestows. I would not know if your chickens would eat it or not it all depends on the birds preference I think they would more likely eat the gourd if at all.
