What Impact Do Sun Rays Have On Chicken?

Direct sun rays into a poultry house lead to an increase in temperature inside the house, which leads to failure of eggs because they receive uncontrolled heat from outside.  The heat can easily make the eggs go bad even before they are picked. Secondly, since the temperature is not controlled, chicken eat less feeds hence reducing in productivity, some of the chicken will scramble for the sun rays, hence leading to a stampede in the house too.
