I started cooling down oct 1st and started introducing my male het lav in with my het pied nov 1st...I know its a very poor pairing but all I have thats ready at this time...my male instantly takes to her and locks are seen almost every time I enter the room. I let him have it for three days then three off. I will do this until feb or march or until I see ovulation....I am not quite sure if this is totally right I am fairly new to this but it seems to work for me...Good luck on your future projects..
