What variables can affect the number of eggs laid by a chicken?

The number of eggs laid by a chicken depends on a number of factors mainly includes the food it is being fed upon and it is properly fertilized or not.

Other factors also impact the egg laying capacity in chicken such as time of the year that means the number of daylight hours effect the egg laying capacity. The breeds of chicken also determine the number of eggs it lays.  The age of hen is also a key important variable in terms of egg laying as maximum eggs are laid in the initial couple of years and then it decreases with age.

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
