External conditions affecting the rate at which the domestic chick gets up on to its toes and walks in the hours immediately following hatching were investigated. Five groups of chicks were tested; four groups were kept after hatching under different conditions (with or without other chicks, under different light conditions and under different conditions of restriction), and one group was hatched under different conditions: each egg was stimulated artificially so that the chick hatched early. The results showed that the last group developed most slowly. The group reared in the light and with other chicks attained the normal chick posture most rapidly, and was followed next in sequence by chicks reared in the light but in isolation. Chicks kept in the incubator until the time of testing developed more slowly. It is concluded that external stimulation can contribute towards, or retard, the development of this behaviour.
