Hi Andrea,
I have responded to your PM, but I thought that it might also be beneficial to post some of my reply on this thread, so here goes;
My initial reply to this would have been not to be worried; firstly, it is not unusual for snakes, particularly species with slower metabolisms such as boas and pythons, not to defacate as regularly. Also, I was going to say it sounds like she is either a)ovulating and in preparation for breeding and therefore will be off feed, or b)just not hungry. Snakes can go for a long time without feeding and I would have initially responded with that.
Also I just wanted to briefly mention the injections you had been advised to give her by the vet; again I would have suggested that it was too early to try these measures and it can also be very stressful for the snake. But it is done now, and will not have done any harm I'm sure, so don't concern yourself with that now.
Regarding the eggs; my first question will be, has she shed recently? If so, then I'm afraid at this moment it is really too late to bother trying to breed from her. Boas have a post-ovulation shed and by the time this has occurred the eggs just won't be much good. If she isn't mated with then the eggs will just be reabsorbed - she will not lay any slugs - with no repurcussions.
If she hasn't shed then I would suggest, if you want to, to go ahead and borrow this male. It is obvious from her ovulation and non-feeding that she is in breeding mode and will be perfectly fine to produce babies. (Just for the record, she will have been ready to breed from around the age of 3years).
Don't worry about the baths and massages; they will not have done any harm to the eggs. They should ovulate once, perhaps twice, in the breeding season, and the eggs can either be fertilised through a mating or will be simply reabsorbed.
Another thing to mention is that if Talyn has had her post-ovulation shed you can still try mating her. She may ovulate again, or if not might produce later in the year, as they can retain the sperm for a long time while it is used to reproduce, so it may not be a waste of effort borrowing the male.
For the record, BRBs cannot "lay" without copulation; they will ovulate, as do all female snakes. It's the equivalant of female humans having a period each month; we are ovulating eggs, which are discarded if not fertilised. But they will not lay any eggs - perhaps slugs I'm not sure - although I would have thought that slugs too would only be layed after copulation. It is most likely that she will reabsorb the eggs.
Our female corns and our female Brazilian Rainbow Boa are all ovulating right now; it's quite obvious for the naked eye to see - the snake becomes quite swollen around the middle area and feels quite squashy to touch. They may also go off feed for a little while, though generally not to the extreme that males do in breeding season.
Good luck if you attempt to breed her Andrea, and I always like to think of these experiences as valuable learning curves; at least you will know what to expect next year and not let her stress you out if she goes off feed again
