Why are cancer researchers studying cruciferous vegetables? Cruciferous vegetables are rich in nutrients, including several carotenoids (beta-carotene, lutein, zeaxanthin); vitamins C, E, and K; folate; and minerals. They also are a good fiber source.
Day 1 - 20 (Incubator) the temperature should be 99.4 F and the humidity should be 83-84 F wet bulb (53% relative humidity). Day 21 - 25 (Hatcher) the temperature should be 98 F and the humidity should be 83-84 F wet bulb (53% relative humidity). When chicks actively begin to hatch (approximately 23Â½ -24 days) increase humidity to 91 F wet bulb (75-76% relative humidity).
Hormonal changes accompany the onset of incubation, with levels of prolactin in the bloodstream increasing and levels of testosterone falling. The ideal temperature for most species to incubate their eggs is c. 38Â°C and this is achieved by developing a highly vascularised brood patch where heat from the body warms the eggs.
