2 years ago I kept all my hatchlings in shoeboxes
Last year someone suggested those little sandwich size "gladwares"~ space saving! So thats what I used
This year someone suggested 8oz deli cups were enough for the first month or so~ even MORE space saving (more babies this year~ I REALLY needed to save space!)
It's not that I didn't put any thought into where to keep the babies. It's that I put A LOT of thought into where to put them. And this year they are in 8oz deli's until they are a month or so old. Then any I still have go into the gladware deli's (not sure how long they can stay there~ some at over 2 months still fit fine).
I use a couple sheets of Charmin TP as the substrate in the 8oz delis. I cut LITTLE disposable cups to size so the babies could get in the little water dishes but they are too tall to turn over. Every hatchlings gets a brand spankin fresh clean deli and water cup every week (and the old delis and cups all get a washing for next week).
If you don't want to cut little disposable cups and use toilet paper as a substrate~ here:
