So I built this 5 tub rack from free lumber I got from craigslist (herpin on a budget!) still have plenty of lumber left and I'm working on a watering system before I build another rack any suggestions would be greatly appreciated. All the female rats had their heat. Some showed sperm plugs when I inspected them and now I'm just waiting to see if they got pregers.
