Do they feed ok?
I ask this because I found that jungle hatchies fed better when pirched above their prey. I therefore used 9 litre upright tubs from the Reject Shop ($4ea from memory) and screwed a branch from one end to the other on a slight incline. This then gave them a) climbing room and b) a pirch to prey off.
I found their eating habits it increase and seemed to be more active.

I would house them individually in these tubs. I wouldn't even consider putting them in a 4x2x2 until they were approx 3 - 4 ft.

Have you thought of dividing the enclosure into 2 seperate 2x2x2 enclosures?

Food for thought.
