Productivity study revealed that Sonali breed was the highest in production number in both the government (GOV) and private (PRI) poultry farms in Rajshahi, Bangladesh. Moreover, Sonali attained the highest production in the fiscal years 2011-12 and 2012-13. The BCF attained the maximum profit (PI=0.646) than PRI (PI=0.114) while the GOV showed negative PI (-0.021) which indicated economic losses. The production profit was gradually decreased from the FY2011-12 to FY2013-14 which indicated economic instability. However, management studies of the chicken breeds among the farms exposed that the GOV showed good management practices (MP) for BW, HR and FM (score 4). The PRI achieved the highest score (3.42=satisfactory to good) for FM while the BCF adopted a lower level to satisfactory MP for all the parameters. The study showed that adopted MP for GOV is better than those of the PRI and BCF. Besides, both the PRI and BCF exposed similar MP at the study area. In addition, disease incidence (DI) studies showed that the GOV achieved the highest score 4.33 (severe to elevated) for SDP. The PRI attained the highest score 2.74 (mild to gross) for BD consistently, the BCF also reached at 1.06 (absent to mild). The DI indicated that disease susceptibility of the GOV was superior in comparison to those of the PRI and BCF in the case of BD, VD, FDC and SDP. The DI parameters showed highly significant difference for BD and SDP (P<0.001). Moreover, the meat yield studies revealed that Fayoumi was the highest for FI and LWG while, Sonali was the highest for FCR. Male chickens showed the highest FI and LWG but the lowest for FCR than the females. The T4 group chicken showed the highest SB followed by T3, T2 and T1 groups. Highly significant difference was observed for LW, TM, BM, LW and GW (P<0.001) among the treatment groups. Furthermore, the egg yield studies showed that Sonali was the highest in EP and indigenous the lowest followed by Fayoumi and RIR. The indigenous attained ASM and APP at lowest production days while RIR at the highest. Conversely, the highest EP was found in T4 group and the lowest in T1 group. The T4 group attained ASM and APP at lowest production days while T1 group at the highest followed by T3 and T2 groups. Finally, it is concluded that the smallholder poultry farmers in the region might ensure sustainable production of their chickens which, in turn, might improve the economic conditions of the growers and nutritional status of the consumers. Owing to their smaller size, popular meat characteristics, low cost and suitability for rearing under prevailing environment, the crossbred Sonali chickens appeared to be commercially viable poultry birds in the study area
