They're the only available source of insects and invertebrates, the protein rich foods hens require for egg development. Without them, a vital link in the food chain would be missing. Madsen illustrates by using the example of a pregnant woman. Yet everyone understands the importance of proper nutrition for expectant mothers. The demand for protein during this period is incredible.
Hens require massive amounts of 'meat' like earthworms, insects and invertebrates.
By the time the big wetlands come to life, the hen is already sitting on the nest. That's why big ponds just don't get it. A lot of policy-makers don't get it, either. Madsen says losing these little wet spots on the landscape would have a devastating impact on waterfowl numbers. Losing them, many experts say, could result in a 50 percent reduction in the fall flight of ducks.
