Breeding in shed?

Alot of ppl tell me this is bad but other people say it is good to breed wile a female is in shed- good or bad

I figure if they lock they lock if not where's the harm..I have some that will breed a garden hose..and others that need a little more of a nudge. Shedding has not been a concern as of yet when it comes to pairing.

I have a bunch of males and females in shed and they are still locking like crazy ;)
