I'm in the middle of building a new coop (the Heather Bullard design) and have a question about the "ground floor". There is an elevated nesting and laying area, but then a larger screened in area they can go out into where the food and water will be. The entire coop with be enclosed in a bigger run that will be 2/3 brick patio and 1/3 dirt. What would be best for the floor of the screened-in coop area where the food and water will be? (and I need to make this decision in the next couple of days, so any help is much appreciated!) My chickens have always had an all-dirt run to scratch and take dirt baths in, but the new design has a brick patio outside the enclosed coop area so I can easily spray it off and not get poop on shoes when we go in and out. That means they will have only 1/3 of the dirt area they used to have to play in. So for the interior screen area attached to the coop I could use the deep litter method where you dig 12 inches down and then keep adding green/garden waste weekly (so it only has to be cleaned 1x/year) or brick, which means spraying it off to clean it all the time. Does anyone have experience with what works better? Also, is pressure treated wood safe for the enclosure? Thank you!!
