The production of "developmental monstrosities" in the species Gallus domesticus has been observed in a number of cases. It is safe to say that few of these "monstrosities" have been subjected to more than a passing investigation or have been recorded in the literature. Perhaps the recording of more complete data on this subject would show that such occurrences are not uncommon. Whether such investigation or the discovery of the cause of such abnormal development would have any part in solving some of the problems of heritage and development is an open question.
