The other day i was at Walmart looking at some tubs because I'm considering switching my corns to tubs. Anyway, i found a very small drawer stack (much like a tub rack) that i thought would be great for a meal worm colony, that way the different stages could be separated and what not, but it wouldn't take up much room. It was around 8 bucks, and the corn meal was 1.50 or something i think. It was the second size up of the drawers that they have. I'm using potato chunks for water right now until (if) i find anything better. Also I've heard they'll just eat the cornmeal, and I've also heard to put some oats in it, so i do just in case and whatever goes in seems to be gone the next day. I have quite a few beetles that have been in there for around a week or so. I need to look the life span of the beetles and hatching time up again so i can decide how long to add beetles to the drawer before moving on to the next so there wont be a bunch of live beetles in with the babies (not sure if they'd eat em or not, just easier to keep everything organized that way so i have somewhat of a count on things). I plan on getting another drawer set up soon (they're designed to stack we'll see how well they actually do) so i can rotate them through the life cycles. and not have to many different sizes/stages together. I don't have any pics at the moment because i keep forgetting to take them. Maybe ill see this post tomorrow while I'm there and remember to take the pics.
