Popis:	This study focused on investigating the reproductive performance of Nigerian indigenous chickens and their crosses with Marshall. The genotypes were normal-feathered (Nn), frizzle-feathered (Ff) and naked neck (Na) chickens, while the crossbreds with Marshall (M) breed were MNn, MFf and MNa respectively (Marshall being the sire while the indigenous are dams).
