Nope, it's on easy, normal speed.Now I'm breeding the 1 female every time I can. I need another male before the 1 I have gets too old. I'm gonna end up with all red heads.( Any body have any problems with inbreeding?)
There is no limit of age for the male making babies. Only the females are limited at 50!

(Don't forget to select as doctors 2 villagers before leaving the game or they will not heal the sick villagers)
