Hey guys! I have several 4X8X4 Hutch type pens that I have been breeding chickens for a couple years in. What do you guys suggest I do to clean them out enough to house my Californias in? I am thinking a good bleaching and hosing, but just want to see if you guys have any other suggestions/ideals. And no, I am not going to bleach it so bad the fumes kill the new inhabitants! So don't ramble off about random common sense aspects like that..
