According to Dalek Sec, there was more than 1000 Dalek-Human Hybrids. All of the Hybrids were later armed with dalek energy weapons that resembled Tommy Guns. Due to the intervention of the Tenth Doctor, the Hybrids had Time Lord DNA mixed up into their genome. As a result of their failing to obey orders because of this, the Hybrids were declared failures by Dalek Caan (who had assumed control over the cult) and were all killed by him - committing a genocide of the entire species.
