Chickens dieting to help Delaware waterways
...ult, about 23 percent less phosphorus is output in chicken
manure. So now when poultry litter is used to fertilize a farm field, a lot less phosphorus is available to potentially leach from the soil or be carried off in storm water to a river or bay. And that's good news for waterways like Delaware's Inl...

senses this compass point by means of its magnetic sense of direction, the researchers set up an artificial magnetic field in an easterly direction and the chickens did actually seek their mother behind the screen that lay to the east. Further ex...
