A total of 118 second generation (H2) C. japonica * C. coturnix hybrids and of 72 Japanese quail (J2) from the same grand-paternal origin were produced and compared for behaviour-related traits, growth, body measurements, feed consumption and efficiency, egg production and egg quality. The H2 had lower tonic immobility (P<0.05) and higher body temperature (P<0.001) than J2 contemporaries. Feed consumption was higher in J2 quail which were larger than H2 birds from 1 week of age onwards (P<0.001), but residual feed consumption R was smaller in H2 males (P<0.05). Relative weights of egg shell and yolk were respectively higher and lower in H2 (P<0.001 and P<0.01). Total egg number (EN\textasciitilde240) at 55 weeks of age and egg laying curves were rather similar in J2 and H2, owing to the laying potential of C. coturnix.
