Famous Lesley Ph.D. Rogers Quote
Recent research has revealed that birds are capable of complex cognition . . . it is now clear that birds have cognitive capacities equivalent to those of mammals, even primates . . . it should be realized that even vastly improved intensive systems are unlikely to meet the cognitive demands of the hitherto underestimated chicken brain. . . . With the increased knowledge of the behaviour and cognitive abilities of the chicken has come the realization that the chicken is not an inferior species to be treated merely as a food source.
