The two major ecotypes of Nigerian indigenous chickens are Fulani and Yoruba ecotypes. The Nigerian indigenous hens exhibit their natural behaviour repertoire, including maternal care. There is a strong bond between the hen and her chicks. Thereby making the importance of maternal care in chickens very essential. Chicks raised without a mother are more fearful and aggressive. The presence of the mother helps to mediate the chicks' responses to stress. Reports on the behaviour of Nigerian indigenous chicks post-hatch are scanty. In this study, we monitored the behaviour of the hens and their brood for the first four weeks post-hatch. The behaviours of interest were chick warming, play-related (mother-chick and chick-chick play), aggression (mother trampling on chicks, maternal aggression towards chicks, mother pecking chicks), and oral-related (feeding, drinking, and foraging) behaviours. Ecotype had no influence on chick warming, but aggressive and oral-related behaviours were greater in the Yoruba than in Fulani ecotype chickens.
