I would like to combine the chickens & ducks come November for ease of maintenance & heating. I am near the Canadian border so winters can be harsh. My birds will be 7 months old; 8 mutt ducks, 2 buckeye & 2 ameracauna chickens, 1 jersey giant rooster. How much room do I need? Will the rooster be a problem? Is this feasible? What other issue should I be considering? TIA
