personally not sure what you are referring to. Viv= Vivarium? = Cage?
Royal = Royal Ball Python = BP?
If I have that right, then I will say, I plan on keeping breeders in Tub not VIV. The VIV I have now will be reserved for my "pet".
As far as breeding, my females will all be in tubs since it is easier to make sure nothing foreign gets introduced to breeders and it is the most stable.
Hope that is what you were asking, if not, disregard. =)
I actually asked the same question a long time ago, most don't because most use rack systems but breeding can be done in a viv they don't really care where they are they will breed if you put male/female together. I don't know how many people do breed in vivs but I know it can be done. Hope this is helpful.
Yea im referring to a vivarium and ball pythons. I do have a rack system and intend on keeping all snakes within this rack.. bar one!!! My first ever one.. i kinda just wanted her on display but she is a female (het clown) and i do intend to breed her.. i just didnt know when the time comes shuld i take her out from the viv to join the male in the rack for breeding the returning her to the viv.
Or bringing a male to her enviornment and returning him back to the rack once finished
