they're just in the breedng cage with nothing but food, water, and bedding. I'm feeding them oxbow adult rat feed for now as this is just a trial run.
I plan on cleaning every wednesday as that's when garbage day is. It's been two days and so far i haven't noticed any smell unless i go up to the cage and put my nose against the bars.
I guess i need to get a lot more females after this trial period is over and everything works out. Thanks guys!
