Eggs, incubation and hatching asynchrony in gulls
… can influence the embryonic development through incubation behaviour because avian embryos develop using parent’s body heat. Although previous studies assumed that incubation behaviour influences hatching patterns, few studies have studied the effect of incubation behaviour during egg-laying and …

Study the effect of eggs incubation parameter through development of new experimental rig for IKTA quails species
… is utilized as an alternative way to hatch eggs, however various temperature settings are used that result in different percentages of hatching between hatcheries. This study aims to investigate the effect of increasing incubation temperature, eggs movement type, and incubation time through …

The breeding biology of Eudyptes penguins with particular reference to egg-size dimorphism
… of 1974-75 and 1976-77. The clutch comprises two eggs, the first-laid (A-) egg being markedly smaller than the second-laid (B-) egg. Components of B-eggs are heavier than the same components of A-eggs. Incubation begins after the B-egg is laid. Incubation of B-eggs lasts 34 and 36 days in …

Broad reduction and adoption in ring-billed gulls (Larus Delaworensis): the potential for inergenerational conflict
… Egg size decreased with laying order; third laid eggs were significantly smaller than first laid eggs. Hatching of the third egg was delayed from that of first and second eggs. Intraclutch egg size differences established initial size disparities among chicks at hatch. Hatch intervals further …

OVERRIPENING OF OVULATED EGGS IN GOLDFISH, CARASSIUS AURATUS L
… physico-chemical changes were observed in the eggs and ovarian fluid. Three stages could be distinguished microscopically and histologically. Morphological changes in eggs included the aggregation of the cytoplasm with the cortical alveoli (CA) and oil droplets (OD) at the animal pole and the …
