First post for a new chicken farmer in the suburbs...we just got five pullets (two Norwegian Jaerhons, one Cuckoo Maran, one Silver Laced Wyandotte, and a White Rock). The kiddos love them and they're thriving in the garage brooder. We got a great deal on an Extreme Cape Cod Coop at CostCo (had a gift card!) but it's clearly too small for more than two or three full size chickens, so I'm thinking of converting it into a tractor to move around the yard. So now I'm in the planning stages for a coop and looking for some advice. We have a fenced side yard where the two sulcata tortoises hang out. The fence is 7' tall with a 5' fence dividing it and the main backyard. I have access to a lot of old cedar fence wood and am thinking about building 7X7 footprint for the coop using the corner of the fence as two of the walls of the coop. There are already three corners of sunk galvanized posts, a concrete footing along one side and 2"X12" scratch pad along the bottom of the fence. My thoughts are to use the DLM on the dirt floor. It seems like this plan would cut down on materials, labor, and costs to make predator proofing easier. Any thoughts on using the existing fence corner as two sides of the coop? Also I am hoping that I can get away with the hens free-ranging in this side of the yard (~15 X35'), and be locked in their coop at night. The yard is pretty well protected from over head intruders, a lot of crows out in the day to harass hawks, a lot of established plant/shrub cover, and we have two big dogs in the main backyard. With five hens and this much space, my concern is whether or not smell be much of an issue (with raking and hosing as needed)? It's up against the house and bedrooms, and I have no idea what to expect. We live in southern CA where it's dry and hot. Sorry for the long post...been reading a lot already on BYC and my head is full of ideas, already thinking that what started with a flock of five might grow eventually...chicken math.
