I usually leave mine for a couple of weeks after they lay the eggs and then show the female to the male without putting her into his cage.
If she acts receptive (doesn't hiss, darken her colors, gape, etc. but moves slowly and calmly) and the male doesn't react with aggressive colors and posture, then I put her in his cage and continue watching them to see that all is well. I leave the female in with the male until she starts to repel him or her background colors are dark.
