While doing a search, I cam across a heated thread, well several, on this topic. Most of the quail owners I know, here in Sweden, have their quail cages by their chickens. I have my quail hutch in the chicken run, as the run is quite large. I see that many have talked about the many diseases chickens are passing on to the quail. I just don't hear about that here. Maybe it is not an issue if the birds are kept in hutches that don't share the ground with the chickens?
