I will still go with them being motherly.If they were gonna kill em they would already be dead.I would leave them for a cpl days see if they get a bit of backbone.If your concerned and you feel the need remove them mate.You say they slept in the court,do you have a sleeping box in their?If you dont and they continue to sleep out there i would get something sorted out.Its getting pretty cold at nights now.Hope this helps.
