I know this thread is a bit old, but here goes my questions.
I live up north in Manitoba Canada, it is super cold here in winter, and I do not have time to build a proper coop right now. I thought I had a ready made coop at my disposal, but does no look that way.
Could I build a similar cage say 3X5X4 feet high, to house 4-6 banties till next summer. The cage and birds would be in my very insulated huge garage. I could keep them a lot warmer than an outdoor coop for dead of the winter temps, and they could have artificial light for laying too.
Not my 1st choice, but could make cages, with perch and nest box. I could even let them outside on nice winter days...
