If you pull the wing out and take a look at the flight feathers you can sex the chick. If all the feathers are the same length then you have a rooster, if you have two lengths of flight feathers then you have a hen. Google "how to sex baby chicks." There is lots of info on this, videos etc. I used this method and have picked them correctly for what I wanted. Good luck. Do know that you can only sex them this way if they are 2-4 days old.
