My friend is breeding her BCIs, and we agreed to build her a "hatchling" rack (I say hatchling b/c I am not sure what baby boas are called.. neonates maybe? I know they don't "hatch.." )So what is a good size for the tubs to be, so they are small enough for baby seurity but will also be good for a few months until they are eating and sold? I really do not know the size of boa babies, this is why I ask; thanks in advance.
