It depends on what you plan to move them into. As your colony is small, you may want to wait a little to move them. However, if you want to, then you can certainly move them into a small enclosure, with a little room to grow, but not too large. Basically, you just want to ensure that they do not treat their nest as a garbage and pile food items inside, as it can lead to mold. (Also, how big/ what species are the ants you are keeping? This will effect the size of the enclosure you should choose) Any photos would help.
Hope this was useful.
