Its hard to say at that age. Is He/she clucking yet? You can tell by the cluck most times. If it is deep or lower its probably a male, and if its light and feathery it is quiet possibly a female. By the looks of it, I would say a male though. Don't trust us people on the internet though! We could all be completely wrong! If your looking to get rid of Him/Her wait until you are sure because it could be a hen!
