The data, sources, and calculations used in the Which dietary changes have the most impact? blog post and the Number of Animals Killed by the U.S. Egg Industry infographic.
Aggregating the above data into yearly sums results in:

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.
