Feathering types of the Hisex Brown day old chicks with different breed belonging, Rhode Island Red- and White-like, were studied by methods of population-genetic analysis. It was stated that the Rhode Island Red-like birds were to a great extent early feathering, while the Rhode Island White-like ones were chiefly late feathering. Such a breed differentiation can be attributed to a ‘founder effect’, i.e. the genetic diversity of initial selection material of different breed origin.

The flight feather growth patterns of 10 lines of Hisex Brown, Rhode Island Red (RIR) and Rhode Island White (RIW) crossbred fowls were compared over a period of 4 years. RIR crossbreds tended to be early-feathering, and the RIW crossbreds were mainly late-feathering, although there were marked fluctuations in feathering phenotype frequencies. The differences between line crosses were attributed to the founder effect.
