Eggs of intermittently incubating birds are periodically re‐warmed by a transient pulse of heat from the parent's brood patch. Estimating the energy cost of rewarming such an egg requires knowledge of the egg's thermal capacity, typically assumed to be the product of the egg's mass and its specific heat, designated here as the gravimetric thermal capacity. When chicken eggs are transiently warmed by an artificial brood patch, the energetic costs of the rewarming indicate that they have thermal… 

Avian incubation Maintenance of egg temperature : steady state

The intention of this chapter is to provide a brief overview of the physical and physiological principles underpinning the maintenance of egg temperature, which have potentially far-reaching implications for the ecology and life histories of birds.

Temperature and life history: experimental heating leads female tree swallows to modulate egg temperature and incubation behaviour.

This study finds strong support for the prediction that intermittent incubators set their incubation investment at levels dictated by energetic constraints, and indicates that females in heated boxes (hereafter 'heated females') increased time spent incubating and maintained higher on-bout and off-b out egg temperatures.

Shedding Light on Bird Egg Color: Pigment as Parasol and the Dark Car Effect

The optimal pigmentation level for a bird egg in a given light environment will depend on the balance between light transmittance and absorbance in relation to embryo fitness, and more pigmentation will increase the detrimental effect of absorbance.

Reverse Engineering of Thermoregulatory Cold-Induced Vasoconstriction/Vasodilation during Localized Cooling

Biological systems, in general, represent a special type of control system. The physiological processes of homeostasis, which serve to maintain the organism’s internal equilibrium against external

Meeting embryonic requirements of broilers throughout incubation: a review

The effects of embryo temperature, egg weight loss, and CO 2 concentration on hatchability, hatchling quality, and subsequent performance are discussed from an embryonic point of view and show that the optimal situation for the embryo during incubation highly depends on the conditions of the eggs before (storage duration) andDuring incubation (environmental conditions) and on theconditions of the chickens after hatching (Environmental temperature).

Individual quality and age affect responses to an energetic constraint in a cavity-nesting bird

There was a trade-off between investing in incubation and maintaining parental condition, but among individuals, there was a positive correlation between change in parental condition and offspring quality, and a strong individual quality effect.

Poultry Egg Incubation: Integrating and Optimizing Production Efficiency

The role of the physical agents of incubation, such as temperature, relative humidity, O2 and CO2 concentration, and egg turning and position are reviewed from an integrated perspective, considering egg incubation as the transitional link between egg and poultry production.

An Experimental Analysis of the Fine-Scale Effects of Nest Ectoparasites on Incubation Behavior

It is found that other factors were the main drivers of variation in incubation behavior, but that eggs in parasite nests were warmer on average, which could help nestlings better cope with parasites upon hatching, and that incubation is a dynamic behavior largely driven by the constraints of maintaining appropriate egg temperatures for development.

Effects of nest quality on incubation and reproductive success in Carolina chickadees (Poecile Carolinensis)

The hypothesis that nest quality would change incubation behavior and that investment in high quality nests would result in higher reproductive success in Carolina chickadees, a common breeding bird in western North Carolina is tested and statistically significant relationships between nest dimensions and reproductive success are found.

Perinatal development and nutrient utilization in chickens : effects of incubation conditions

Positive effects of suboptimal incubation conditions can be partly explained by changes in nutrient utilization and metabolite levels in the perinatal period and can have long-lasting effects on the survival and performance of broiler chickens.
