Aggie in the Feed Store

An Aggie goes into the feed store and tells the owner that he was starting a chicken farm and needs to buy about 500 baby chicks. The feed store owner sells the Aggie the required number of chicks and wishes him luck. Two weeks later the Aggie buys another 500 baby chicks from the feed store. Another two weeks goes buy and the aggie returns to the feed store for yet another 500 chicks. The feed store owner says "Boy your going to have one large chicken farm with 1500 chickens!!" The Aggie answers, "Not really, I haven't had much luck. Not sure if I'm burying them too deep or just too close together."
