That doesn't sound crazy, more like dumb
Males at 6 weeks old have no business being put with any female.
Palpate her and keep palpating and if the male isn't ready when she goes into glow put another male with her.
Why not, he was producing plugs and the female took. You shouldn't put him with multiple females. But if he's ready to go I see no adverse problems. It's not like breeding a female that is too small.
