The Sexual Behavior of Hormonally Treated Domestic Fowl.

Both androgen and estrogen, injected into capons, induced the masculine copulatory behavior but only androgen induced crowing and increased or induced the “tidbitting” and “waltzing”. In bilaterally ovariectomized poulards, androgen induced crowing and waltzing but did not induce the masculine copulatory behavior while estrogen, on the contrary, induced the feminine squatting behavior. These results would seem to suggest that certain behavior patterns are common to both sexes of the fowl and may be induced by the appropriate hormone. The masculine copulatory behavior can be induced by both androgen and estrogen but only in genetically determined males.
