The aim of this thesis was to compare turkeys’ behavior from two separate genetic groups, being reared semi-intensively. The willingness of spending time on the run, the relations between the birds, reaction to wild animals and human presence were analyzed. Big-6 hybrids were more sensitive to weather changes, they were characterized by a lack of reaction to potential perils of the predators and were too trustful towards humans. As compared to these birds, primitive turkeys’ behavior was similar to the behavior of wild birds’ ancestors of the discussed breed.
