I have my brooder in the laundry room. The birds are almost 6 weeks old and doing great. We hope to move them outside to the new coop this weekend. I have been using the deep litter method, horse pellets and DE, but we are starting to get quite a bit of dust and odor. I cleaned it out and the smell is gone, but I was wondering, at this point could I open the window a bit? The window is above the brooder, and while they still have the heat lamp it is at 75, and it is 78 in the room.
