EvaMarie,
If your specimens are adults and if the females are in reproductive (robust) condition, at this time of year you should be able to run your thumb down the ventral surface with a slight pressure and count the ova. And if both the male and either female are in the reproductive mood, by placing them together the male would then court the female or females.

I have never tried not having my boas undergo brumation at the normal time. I don't know for certain but suspect it may be necessary for the species undergo brumation before they will successfully breed and produce young.
