Sažetak
Križevci crested hen was created in the 1980s through selective work on domestic hens grown in Kalnik hills, which was characterized by crest and medium-hard body. These hens were crossbred with Orpington breed roosters. Until now, there have not been any scientific researches to gain knowledge about their phenotypic and production characteristics. Therefore, the aim of this study was to determine the values of physical measures of hens and roosters and the appearance and quality of eggs in order to start creating breed standards required for its recognition as a native breed of hens. The study involved hens and roosters from four family farms in the town of Križevci. The color of feathers, legs and ear lobe in animals aged between six months and one year was determined and animals were weighed. Values of ten body measurements were recorded. Eggs were collected to determine egg mass, shell thickness, the share of egg yolk, albumen and shell, and color of albumen. Križevci crested hen has a harmonious square shaped body and lavish black bordered yellow feathers. The head is of medium size, there is a crest with orange-yellow color in roosters and black-brown in hens. The mean body mass of roosters aged 6 and 12 months was 2.33 kg and 2.95 kg, and in hens of the same age 2.06 kg and 2.71 kg, respectively.
