Ya you are right it is early...you have PLENTY o time for locks. Seperate your animals for a couple weeks, and the next time you have a male shed, check the shed for spermplugs. Take the spermplugs from the shed and rub them on the back of the female. Make sure you are using the shed from a different male. Then when you introduce your breeder male, he will smell the other male and hopefully get his motor running. I have heard people just throw the whole shed from the other male into the cage with the female and have gotten results. Good Luck Bud!
