I am not a breeder, but, when the color of her discharge lightens to a pinkish-tan color (usually around 9 - 12 days after her starting her cycle) her vulva will be soft and you'll notice her flirting with your male. Your male will determine by sniffing and licking when she is ready to be bred. If you own the male you will notice a change in his behavior and his lack of appetite, he'll only have eyes for your female and will not want to do any of his normal activities, even go outside. Lots of whining and restless nights when you have a female in season.
