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… Expand

Avian incubation Maintenance of egg temperature : steady state
Contact incubation of eggs is one of the most conspicuous features of avian biology. Its purpose is the maintenance of a warm and steady egg temperature, and during incubation, the parent bird… Expand
Temperature and life history: experimental heating leads female tree swallows to modulate egg temperature and incubation behaviour.
TLDR
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. Expand
Shedding Light on Bird Egg Color: Pigment as Parasol and the Dark Car Effect
TLDR
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. Expand
Meeting embryonic requirements of broilers throughout incubation: a review
TLDR
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). Expand
Individual quality and age affect responses to an energetic constraint in a cavity-nesting bird
TLDR
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. Expand
Poultry Egg Incubation: Integrating and Optimizing Production Efficiency
TLDR
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. Expand
Effects of nest quality on incubation and reproductive success in Carolina chickadees (Poecile Carolinensis)
TLDR
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. Expand
Perinatal development and nutrient utilization in chickens : effects of incubation conditions
TLDR
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. Expand
SOLAR HEAT ACCUMULATOR CONTROL APPLYING REFLECTIVE ARRAYMETHOD FOR ENERGY OPTIMIZATION
