They are staying outside during the day and inside at night for now, I am getting my breeder cages saturday then they will be split into trios. I have a small metal shed that I built, it is 4ft wide x 6ft long and 6 foot high. I built it to house garden shovels and things, I am considering making a shelf of sorts to support the breeding cages and hang a metal heat light fixture with a 150w spot bulb over them for the winter, I was going to put plastic on the inside of the shed to keep drafts down and possibly even insulate it. I LOVE these coturnix already and I want them to have the very best, their little personalities are so cute, I think the guy I got them from held them because they dont mind being held, actually seem to enjoy it and I have a dozen of them lol
