The laying hen excretes relatively large quantities of iron in the eggs. In our experience, a weekly output of 6 mg. Fe is not uncommon, and a good layer may lose 150-200 mg. in a year. This loss, which is not suffered by the non-laying bird, is so great that interesting changes in the processes of iron metabolism must precede or accompany the onset of laying. This paper presents the results of some in-vestigations in this field.

Influence of laying on iron metabolism in quail.
Quails fed on an iron-deficient diet distributed iron preferentially to the haematopoietic processes, at the expense of the iron content of the eggs and a subsequent reduction of viability.
Serum Iron and its Transport Mechanism in the Fowl
Iron in the blood is attached to β1-globulin (transferrin or siderophilin), the transport mechanism of which seems to be common to higher vertebrates; but it is found in the hen bird that there is a special behaviour during the laying season.
Serum Iron Transport in the Fowl and the Mammal
It is known that in the vertebrates serum iron is transported as a transferrin complex and thus metallic toxicity in the ionic form does not occur, but the existence of conalbumin1 has been demonstrated in the serum of hens and Immunological assay shows them to be identical.
Iron metabolism in iron-deficient male quail.
Intestinal iron absorption in chickens
Sexual differences in intestinal iron absorption in Shaver and New Hampshire chickens strains was analyzed with an in vivo perfusion technique in closed circuit, and a thicker intestinal wall seemed evident in the adult females, with highest values during laying.

Physiology of the growing and adult goose. 3. Some nitrogen constituents of blood.
Levels of serum albumin and globulin, and therefore total protein, increased with age from 1–20 weeks, and non‐protein nitrogen declined through this period of the goose growing phase and the first reproductive cycle.
Sexual and age variations of organ iron content in Shaver chickens.
The iron contents of both heart and kidneys were influenced by age and followed a linear trend, except that in the heart of females where a quadratic response was observed.
