Thanks for your response Bettacreek, I'm sorry if I didn't make myself clear. If I divide the whole structure into four sections instead of just two they will all be isolated, no ramps or anything. Each colony section (the bottom) will be 5'x2'x10" (LxWxH) each one to have it's own drop pans, etc, and house no more than 10 birds. There would be 4 breeder cages, each 2.5'x2'x10", each one to house no more than 4 birds, preferably 3 (one cock and two hens).
As a side note, do coturnix REALLY stink as bad as some folks say they do? We brought our hens into the basement for hurricane Sandy, and admittedly, they were a bit ripe after a couple of days. I wouldn't want them living in the house again unless it was a Boston/Nemo-style 36" snow storm, and even then only for the very short term.
Either way, at the moment, we are planning to keep the coturnix in our basement, rather than outside and exposed to elements, neighbors, predators, etc. And I'd like to know if the stink is truly that bad, or if, with proper management and stank reduction techniques, guests would still want to come to my house.
Attached below is a pic of the whole thing still in progress. Its all in my basement now, but if I finish it down there, we probably won't be able to get it out to the garage without some major pains in the butt (i.e. sawing the top half off the bottom half to fit it out the door). Any suggestions on completing the structure as would best fit the max space per bird and stank reduction protocol would be much appreciated.
Thanks! - Suzi-Q
