Effects of hatching system on chick quality, welfare and health of young breeder flock offspring
Poultry Science, 2023 : Alternative hatching systems have been developed for broiler chickens to provide immediately feed and water after hatch and reduce the number or severity of early life stressors. Besides beneficial effects of these alternative hatching systems on chick

Molecular and morphological analyses of avian eggshell excavated from a late thirteenth century earth oven [PDF]
, 2011 Using ancient DNA (aDNA) extracted from eggshell of the extinct moa (Aves: Dinornithiformes) we determined the species composition and number of eggs found in a late thirteenth century earth oven feature at Wairau Bar (South Island, New Zealand) - one of

Improving eggshell quality at high temperatures with dietary sodium bicarbonate
Poultry Science, 1997 Two experiments were conducted that confirmed the hypothesis that a dietary bicarbonate supplement will improve eggshell quality in hens at high temperatures as long as feed is consumed during the period of eggshell formation. End-of-lay hens were maintained on continuous light at temperatures of 30 and 35 C.

Eggshell appearance does not signal maternal corticosterone exposure in Japanese quail: an experimental study with brown-spotted eggs [PDF]
, 2013 Reproduction is a critical period for birds as they have to cope with many stressful events. One consequence of an acute exposure to stress is the release of corticosterone, the avian stress hormone.

Effect of Room-temperature, Calcined Eggshell Reactants on Synthesis of Hydroxyapatite [PDF]
Journal of the Korean Ceramic Society, 2015 Synthesis of hydroxyapatite (HA) was attempted through a room-temperature reaction of calcined eggshell with phosphoric acid. Ball-milled, calcined eggshell powder, which has a specific surface area of 31.6 ㎡/g, was mixed with various concentrations of phosphoric acid at room temperature.

Environment type and storage period on eggshell quality of laying hens at different ages
Ciência Rural, 2021 : Eggshell quality is directly linked to the good acceptability of the product by consumers, whereas the industry is concerned with economic losses. Prolonged periods of laying, diseases, nutrition, bird age and genetics can influence egg quality.

Experimental increase in temperature affects eggshell thickness, and not egg mass, eggshell spottiness or egg composition in the great tit (Parus major) [PDF]
General and Comparative Endocrinology, 2019 Phenotypic effects of global warming have been documented in many different taxa. However, the importance of transgenerational phenotypic plasticity in these adaptations are seldom studied. In birds, temperature could affect egg characteristics. Higher temperatures during egg-laying may reduce maintenance costs for females and allow a higher investment
