Hi All, I will be moving my coturnix quail outside. I have a 3ft by 3ft brooder that I will put inside a dog run 4X8. I live in NY on long Island. so I'm wondering about heating for them? How far should they be away from my chickens and ducks? Should I be locking them in what will be there coop at night? I hear they are stupid as far as knowing to coop themselves at night. how large or small should the doorway be open for them? Any help or suggestions is appreciated.
