This method works for hatching eggs from sex-linked breeds where male and female birds have different color plumage, all males white-feathered and all females brown-feathered for example ...
However, the rate of development can be affected by a range of factors; including the specific breed, the temperature of incubation, the delay between laying and incubation, and the time of year, raising the need to create a standardised system based on morphology rather than chronological age.

During the last few days of incubation, the residual yolk is retracted into the body cavity as an extension of the intestine. Post hatch, the residual yolk is the only nutrient source of the chicken until exogenous feed is available. Chickens can use the residual yolk for maintenance during the first few days post hatch.

Even in other birds, ambient temperatures can lead to variation in incubation period. [7] Normally the egg is incubated outside the body. However, in one recorded case, the egg incubation occurred entirely within a chicken. The chick hatched inside and emerged from its mother without the shell, leading to internal wounds that killed the mother ...
That is down considerably from a peak of 7.2% in June 2022 but still above the Fed’s 2% goal. When excluding volatile food and energy costs, the so-called core PCE was down to 2.8% in November ...
