Further Studies of the Effects of Selenium Poisoning on Hatchability
TLDR
In this article, Tully et al. reported the results of experiments which demonstrated that high chick embryonic mortality in certain localities was due to deformities in the chick embryos, and these deformities were caused by the feeding of grains containing selenium to the hens.About:

Embryonic mortality and abnormalities of aquatic birds: apparent impacts of selenium from irrigation drainwater
TL;DR: Severe reproductive impacts were found in aquatic birds nesting on irrigation drainwater ponds in the San Joaquin Valley of California, and aquatic birds may experience similar problems in other areas where selenium occurs at elevated levels.
Journal ArticleDOI
Biogeochemical cycling of selenium in the San Joaquin Valley, California, USA
TL;DR: Subsurface agricultural drainage waters from western San Joaquin Valley, California, were found to contain elevated concentrations of the element selenium in the form of selenate.

TL;DR: The irrigation history of the San Joaquin Valley (Valley) is composed of several phases starting with individuals digging ditches and continuing to the present State Water Plan as discussed by the authors, which has produced an enormous rise in the number of farms, population, and harvested acreage in the Valley.
Journal ArticleDOI
Impaired reproduction of mallards fed an organic form of selenium
TL;DR: The dietary threshold of selenium as selenomethionine necessary to impair reproduction is between 4 and 8 ppm, which indicates that when eggs from a wild population contain > 1-ppm Selenium on a wet-weight basis, reproductive impairment may be possible and should be evaluated in that population.

Kurt W. Franke,W. C. Tully +1 more
TL;DR: The lengths of time between fertilization and the first cleavage and the rates at which the early cleavage follow one another may differ decidedly among the eggs of even closely related forms, and are probably fundamentally connected with differences in chemical structure of the egg substances.

W. C. Tully,Kurt W. Franke +1 more
TL;DR: It was decided to raise chicks to maturity by feeding them affected grains, and then if possible, secure hatchable eggs, in this way the question of unknown stock would be removed.

TL;DR: In addition to hindering growth it was shown that 65 percent of the toxic grain in the diet delayed egg production almost two months after these chicks had reached maturity.
