i have a single conturnix hen and winter is coming on. we are having temperature drop into the teens, do i need to put a heat lamp in her box or will she be ok with pine needle bedding out of the cold wind. and do you think i should get some company for her. i originally had two a male and female. she did not do good with the male, he would chase her around and be mean to her. he disappeared when i was cleaning the coop one day.
