Chickens and Leafy Spurge

[precords]

We are planning on getting chickens and keeping them in a chicken tractor. We have some leafy spurge plants on various spots on our land. Leafy Spurge is supposed to be a toxic weed. Will the chickens get sick or die if they eat it? Could also use ideas on how to get rid of the leafy spurge altogether. Thanks in advance for any help. :)
