It can be assumed that for each layer pullet added to the flock, a male chick was hatched. That is, there were around 289,780,000 male chicks hatched in 2014 (see Total Number Slaughtered, Lost, and Added — United States: 2013 and 2014 above), and it can be assumed that nearly 100% of those were culled.
