Most American lamb is confinement finished also (complete with hormones, grain feeding, and antibiotics). Check to see whether it says all-natural, hormone free, or New Zealand.
American chicken does not contain hormones. It's illegal. Antibiotics, however, are present, as are high levels of salmonella and high acidity associated with grain feeding.
Judge by the individual brand and MOST importantly what's better for your dog. Chicken is often more easily digested but lamb has higher levels of lineolic acids and natural GAGs. Lamb is also often better accepted by dogs with food sensitivities.
