A study has been conducted on a total 1200 no. of chicks out of which 600 numbers (200 each of Indigenous, Vanaraja and Crossbred) were reared under intensive system. All the types of chicken were fed uniform diet of Chick (0-8 weeks), Grower (9-20 weeks) and Layer (above 20 weeks) ration prepared with conventional feedstuffs as per BIS (1992). Remaining 600 numbers (200 each of Indigenous, Vanaraja and Crossbred) were distributed among 30 beneficiaries for backyard system of rearing. The overall egg weights at 40 weeks of age were significantly (P≤0.05) higher in Vanaraja (53.65 ± 0.57 g) followed by Crossbred (44.6 ± 0.55 g) and Indigenous (34.60 ± 0.28 g) chickens. Similarly the overall egg weights at 40 weeks of age was significantly (P ≤ 0.05) higher under intensive system (45.10 ± 1.51 g) than under backyard system (43.47 ± 1.34 g) of rearing. The shape index was found to be higher in indigenous than Vanaraja and crossbred chicken. Significantly (P≤0.05) higher values of egg weight, egg shell thickness, egg yolk index and H.U scores of eggs were observed under intensive system of rearing than those under backyard system of rearing. However, rearing systems had no significant effect on shape index and albumen index values of eggs. It can be concluded that the Vanaraja could be reared successfully under backyard system of rearing for increasing egg mass.
