I would agree that you should wait til he sheds. I also move my males to the females. I don't want to stress the females if I can help it. I boys in with the girls and periodically check for locks. Boys are in for 3 days and out for 4. I rotate to other females following this routine, I also offer food on the off days. Also, if (when) you get locks, try to minimize interuptions. Take a picture or 2 then leave them alone to get it on.
