Chicks raised by a broody hen can see social fellows (mother, sibs) to whom they might attach, only during emergence from under the mother. Chicks raised by a hen showed longest emergences when in broods of 1-2, shortest in broods of 3-4 and longer again in broods > 4. As a result, the first visual experience of any length was on day 2 for broods > 4 and on day 3 for broods of 3-4. Mean duration/chick was 45-50 min in both cases, comparable to times found to give attachment to models. The mother's moving (and often calling) head must be a dominant visual feature for chicks: they most commonly emerge from under the breast and are at once confronted by it. When they emerge from under the wings, the mother turns the head to them, and they then accompany it back to the breast, where they nearly always re-enter. The first experience of the mother in translatory motion on day 5 is so different from this that it probably leads to further learning. Chicks reared in groups without a mother learn to discriminate sibs from strangers. If this occurs in normal broods, it could begin in the group emergences, which are usual on day 3.
