I live in Central Missouri so our winters periodically get very cold. I have two roosters that I would like to winter – gorgeous boys - but I don’t have an established house they can winter in because the established roosters won’t allow it. I would like to keep them. The two boys can’t winter together because they fight but I’d like to keep them for breeding stock next year. I have 2- twelve square foot (3’ x 4’) houses so each one could have his own house but I do worry they’d freeze to death. The houses are well built – two layer, cedar siding over particle board. Good light and good ventilation. Any thoughts of if a single bird with plenty of straw could survive sheltered in 12 square feet?
