Will weed seed pass the chicken gut undigested and contaminate fields using manure fertilizer? Amaranth and ragweed?

98% of weed seeds are destroyed by the chicken digestive system. If you are feeding grain, grinding the feed will further help reduce seeds consumed. If the chickens are pasture raised, reduce the weeds present in the pasture. Composting manure will kill all seeds if heated to 180 degrees for at least three days.

Here is a great resource on the issue: http://www.uwex.edu/ces/crops/uwforage/Weed%20Seed%20Survival%20in%20Livestock%20Systems.pdf
