Effects of chick separation and feeding on the performance of hens and chicks

Abstract

A study was conducted to observe the effect of separating chicks from broody hens after hatching, and supplementary feeding, on the performance of broody hens and chicks. Eighteen broody hens incubated 360 eggs of native hens. Broody hens and chicks were divided into three treatment groups; in T₁, chicks were not separated, and chicks scavenged with mothers; in T₂, chicks were separated at five days and fed ad libitum; and in T₃, chicks were separated at 10 days and fed ad libitum. Hens in T₂ and T₃ received 50g feed/hen/day. The interval between end of incubation and first lay was shorter in T₂ (36.3 days) and T₃ (41.7) than in T₁ (55.2). Clutch length was shortest in T₁ (12.7 days), medium in T₃ (15.0) and longest in T₂ (17.0). There were more eggs/clutch in T₂ (14.7) and T₃ (14.3) than in T₁ (11.5). There were no differences in broody hen's body weight between treatment groups. Mortality of chicks was highest in T₂ (39.6%), medium in T₃ (33.9), and lowest in T₁ (21.0). Body weight of chicks was highest in T₂, medium in T₃ and lowest in T₁, except at 1^st week of age. It is suggested that separation of chicks and supplementary feeding was beneficial in terms of interval between end of incubation and first lay, clutch length, number of eggs per clutch and body weight of chicks.
