My quail live in a 4 X 3M reinforced wire pen on a grass floor with a tarpaulin cover to make the roof. I've made 3 hide away boxes of different sizes and shapes and filled them with nice warm and cosy wood shaving and hay bedding to keep them warm in the winter. Its currently -5°C most nights at the moment and the idiots spend all of the night sitting out in the open. I thought they would want to huddle together in the boxes to keep warm but they don't seem to use the boxes at all. I've even tried putting food inside them to tempt them in but they just go in and eat the food and then come out again. Should I be doing something else for them or are they quite happy out in the cold all the time? They are eating and drinking and seem fine but no one has laid an egg since end of November.
