At which stage the egg of Chick is laid?

In birds, fertilization occurs about 24 hours before the egg is laid. The newly formed single cell begins to divide into 2, then 4, 8, 16, 32 and so on. At the time of laying, hundreds of cells are grouped in a small, whitish spot (the blastoderm or germinal disc) that is easily seen on the surface of the yolk.

Is the heart beating in 33 and 72 h chick embryos?

The heart of the chick embryo develops from the fusion of paired precardiac mesodermal tubes between 24 and 29 hours of incubation. As fusion continues the atrial portion of the heart is incorporated, and the rate of the heart beat increases because of the controlling cells of the atrium (33 hours).
