Coturnix outside in New England

[tomorton]

I have 4 male and 11 female coturnix I am keeping outside here in southern New England..they have lots of shelter in their pen..straw covered  lean-to's..natural brush and a thick layer of pine shavings.  Is this adequate for them in this climate?..I can't seem to find definitive information.  Meantime the 8 buttons I was shipped in error are living in my garage..:)
