I upgraded my tote to a playpen when they were about 3 weeks old. What an awesome upgrade and awesome amount to clean! I was throwing sod into their brooder so they got some grass and scratchy and bugs. It was way to cold in CT mid May to bring them out. When i moved them out, i had about 3 inches of scratched sod/dirt in the playpen, in my living room! Dust covered everything and when i went and set up the shop vac to suck it all up; guess what???? I had it turned onto BLOw! That initial moment when i turned it on, in my living room, and all that dirt and dust took flight. Oh my.....i was happy doing a deep clean tho, the girls were in their new coop!
