It has been close to four years since I first considered getting chickens. I have not done because of many of factors, some of the biggest being that I never thought I could get a coop and run built that would be small enough to fit the yard, escape the neighbor's notice and still be good for chickens. I always leaned to a smallish coop that looked like a dog house or rabbit hutch-Eglu proportions but made at home out of cost effective wood. I also feared the usual noise of even a tiny flock of 3 birds would be too much. Then I had a brain storm-what if the coop wasn't outside? My garage faces the backyard. I have an over head storage unit in one corner that has an open space of 8'X4'X4' beneath it. That is the place the mower and wheel barrow get parked now-why not enclose it and that would be the coop area-the place for food, water, roosting and laying. A pop hole in the wall would give access to freash air and sunshine. I can do a 4'x6' run, with free ranging when possible. I can see some advantages to this arrangement-more space per bird, better temperature control in winter ( no frozen water, or going out in the freezing cold to feed birds or collect eggs). A deep litter system would give great compost. I'd be interested in more experienced hen keepers thoughts and suggestions. How solid would and indoor coop area need to be? Any draw backs I may not be thinking of?
