The study was conducted to compare early sexual maturity characteristics between Bovan Nera and Isa Brown Parent stock chickens reared in a commercial breeding system in Ibadan, humid Tropical Nigeria. Records on Pullet weight at 10 weeks (PW10, g), Feed-intake at 10-weeks (FI10, g), Total feed intake from11 weeks to first egg (FI11FE, kg), weight gain from 11 weeks to first egg (WG11FE, g), Feed intake at first egg (FIFE, g), pullet-weight at first egg (PWFE, g) and pullet-age at first egg (PAFE, days) were culled from the parent stock breeding farm records of CHI Farms Ltd. Ibadan; covering 1999 to 2008. The effect of PW10on FI10, FI11FE, WG11FE, FIFE, PWFE and PAFE was investigated. A total of 20 flocks of each strain were compared. Data were analyzed using ANOVA, GLM, Tukey’s T-test, correlation and regression procedures of SAS® (1999) in randomized complete block (RCBD) design. Findings revealed that three body weight classes at 10-weeks (900 g) caused significant differences between strains in WG11FE, PWFE and PAFE. The 701-800 g body weight group produced no significant (p>0.05) difference between the two strains. PWFE was positively related with PAFE in BN (R2=0.11) and IB (R2=0.71). Strain averages revealed significant (p
