In the Biologisches Centralblatt we find a few interesting data relative to the influence upon the embryo.
During the course of an artificial incubation Professor Maggiorani submitted a certain number of hens eggs to the influence of powerful magnets, taking care in doing so to keep at the same time an equal number of eggs away from all magnetic influence. The result was that, in the first group, four times more eggs were arrested in their development than in the second. After being hatched, three times more died out of the products of the first group than those of the second.
Among the survivors, those of the second group all developed normally, while out of the first, sixty exhibited numerous imperfections or abnormal movement. Six chicks only of the same group reached maturity, and among these six two were cocks of remarkable size and appetite. Of the four hens, one never laid eggs, and the others laid very small ones weighing about an ounce, and incapable of producing living beings.

Story Details
Professor Maggiorani conducted an artificial incubation experiment on hen eggs, exposing one group to powerful magnets and keeping another as a control. The magnet-exposed group showed four times more developmental arrests, three times more post-hatch deaths, and survivors had imperfections or abnormal movements. Only six reached maturity, with two large cocks and four hens that laid small, non-viable eggs.
