In this Tuesday, Sept. 26, 2017, photo, Tanya Keith, of Des Moines, Iowa, and her daughter Iolana feed their chickens in the backyard of their home, in Des Moines. The trend of raising backyard chickens is causing a soaring number of illnesses from poultry-related diseases. For Keith, the nine hens and a rooster that she keeps behind her home provide fresh eggs and lessons for her three children about where food comes from. But even as her kids collect eggs and help keep the six nesting boxes tidy, she warns them not get too affectionate. (AP Photo/Charlie Neibergall)
