Hi All,
I'm new here and I thought I would ask a question. I breed the common wood roach (woodies) for food for my reptiles. I have a large tub full of them. I want to be able to sort them into different sizes and start new colonies with roaches of the same size. Can anybody tell me the best way to sort the roaches into different sizes so I can start new colonies.

Thanks

Here's an older post with a suggestion:

One common method is the use of multiple cages and rotation. A number of gravid females are moved to a cage where they lay eggs or give birth and then are moved to a new cage ensuring that only one size is in the cage.
