So I’m taking the dive, my wife doesn’t want any mammal pets inside the house other then the dogs or cats. I’ve been doing research on this topic and it appears feral parakeets in the US are fairly prolific in some north eastern states(I’m in MD). 3 sides of my aviary is solid. I’m adding some insulation then covering it with these thick plastic sheets I get from my job. The front being wire so far I have half of the left side covered with plastic. Do y’all think I need to cover that whole left side, bottom of door and the bottom right side during the winter. I can always take the plastic back off during the summer. Any other things y’all think I should add. Heat lamps will only be used doing -0 degree weather
