Lohmann Brown chickens stand outside a barn at Meadow Haven Farm, a certified organic family run farm, in Sheffield, Illinois, U.S., on Tuesday, Aug. 4, 2015. U.S. egg prices, already at a record after an outbreak of avian influenza earlier this year, will rise even higher in the fall with the onset of the so-called holiday baking season, according to one supplier.
