Are tomato vines seriously poisonous?? My chickens have been eating them for the 6 years that I have been raising them, and I never noticed any problems with my birds, they gobble them up like candy...never had one get sick from them. They just eat the leaves though, and not the stems...pepper plants too, when those are done in the garden, I pull them out and let the chickens have at them...I know not to give potato peelings as I heard that upsets their tummies, and dont give anything that has a strong odor as that will flavor the eggs, onions, broccoli, garlic, etc...
