I live in Illinois where we have large temp swings. Winter down below zero and in summer up to 100. I was thinking of puting in a aviary outside to keep birds in. I know quail do well since I raise them. So will have some in there but I was trying to think of birds that would do well in cold with shelter and heating. Would prefer to keep in there year round but if need be I’ll bring inside during winter. Was thinking budgie, and finches but those would be birds that I bring in when it gets cold. Any idea on cold hardy birds?
