There were no significant differences in egg mass (EM) among all main and interaction effects. Though insignificant Kk chicken attained 6 days earlier in the age at onset of egg laying (AOEL) and significantly (P<0.05) earlier AOEL was recorded in the main effect supplemented and the interaction effects of BB breeds due to supplementation.
