Salatin is criticized by poultry farmer Frank Reese in Jonathan Safran Foer's book "Eating Animals" for raising industrial birds, not heritage birds. Reese says of Polyface, "Joel Salatin is doing industrial birds. Call him up and ask him. So he puts them on pasture. It makes no difference. It's like putting a broken-down Honda on the autobahn and saying it's a Porsche." Salatin maintains that this statement is not entirely true. Polyface uses heritage breeds for its egg production. However, for meat birds Salatin uses the Cornish cross, the same type of bird used in the industrial system. Salatin candidly admits in his book, "The Sheer Ecstasy of Being a Lunatic Farmer", that the meat bird operation is currently the least sustainable aspect of the farm. Salatin goes on to say that he looks forward to the day that customers are willing to buy (and he is able to raise) a non-industrial meat bird. Reese's critique also aims at Michael Pollan's view in his book "The Omnivore's Dilemma" that depicts the farming principles of Polyface as exemplary and sustainable. Salatin confirmed, in an interview with "The Observer", that he raises non-heritage breed chickens. He explained that he had raised heritage birds for several years, but the poultry from these birds had gained little interest from consumers, and was therefore not economically viable for him.
