I second the females not breeding during shed period, mine simply won't

You definitely broke quarantine and it's too late now but I'd brush up on how to properly quarantine for future practice.

Also as Freakie Frog says, moving females before or during breeding season means you may be waiting till next season whether you want to or not.
Keep trying for awhile giving 2-3 day breaks in between pairing and offer food during this break.

Reading is wonderful, sadly nobody lets the snakes read the manual so they rarely follow what you read
