I've now seen quite a few of the posts ... wondering if I really need all 4 houses; I guess we'll see. We're looking for full size layers (breed yet to be determined); am in the pacific northwest.
Hubby and I are disagreeing about how much house space is needed and how much yard space is needed; and actually, how tall the fence needs to be for the yard space. And ... if we have them near the front yard (where the houses would be shown off the most) if someone will come and steal either the chickens, the eggs, or the houses themselves. Keep in mind we live in a small town, not a particularly high crime area, but he's kind of a negative nelly kind of guy.
So ... what I'm thinking about is building a platform, about 3-4' off the ground to set the houses on. Having 3 of the houses side by side (with two of them sharing a common wall, the third would have all walls in place, with a closeable chicken door between that third building and the other two so I could close that building off if I needed to sequester some birds). The people doors (front of the buildings) would be facing out. The "plain wall" would be facing the chicken yard. The floor would have two closeable doors in it with ramps that would go under the house floors (so part of the yard is covered by the houses, the rest would be open air (but covered with fencing material incase of predators) - one of those doors would be in the somewhat separate building, and one would be in the double building. We don't really have a substantially large number of predators, but I'm sure between the cats, hawks and the coyotes that might be attracted, they'll need some protection.
The yard would be 12' wide (3 buildings) and about 16' long. It would be 3-4' high (so it wouldn't cover the buildings at all, would be relatively level with the platform floor of the buildings). My thoughts are that the houses would look like town houses with garages underneath (well, not really garages, because that would be the fenced area). I hope to be able to "turn out" the hens to be loose on our 5 acre property during the day at least 5 days a week.
I'm looking for enough hens to have my family (2 adults, one teen) kept in eggs, plus enough to sell to pay for the feed and recover the startup costs within 18 months (costs expected to be no more than $750). Home-grown eggs in our area sell for $2.50-$3.50 a dozen.
I was thinking our setup would be appropriate for 15-20 hens?
