The average heart rate of the chick increases from 286 beats/min. at 1 day to 475 at 1 week, with the greatest change occurring during the first 3 days. Heart rate continues to increase slowly to a maximum of approximately 500 beats at 34 weeks,
then declines gradually to a stable adult level between 280 and 350 at about 6 months. Between the 12th and 17 weeks, the heart rate of the male dropped 1012% below that of the female, approximating the sex difference found in adults. Heart rate measurements on gonadectomized and gonadotrophin treated birds failed to indicate the role, if any, of gonadal hormones in the development of the sex difference in heart rate.

By studying chickens' hearts, a University of Missouri researcher has identified certain proteins within the heart muscle that play an important regulatory role in embryonic heartbeat control. Understanding these components and how they interact will give researchers a better understanding of heart development and abnormalities in humans.
In the study, researchers examined embryonic chickens' hearts, which develop morphologically and functionally similarly to humans' hearts, and tested the electrical activity present in the cardiac muscle cells over a period of 24 hours. They found that changes in local proteins have important effects on embryonic heart beat control.
