All are 5 weeks old. Time to leave the living room. Do the ducks need a water source during the nite, or can I let them go through the nite without water (preferred) Will the chickens and ducks co-habitat well? They hang out together outside when we take them out, but the ducks are aggressive with the chicks. I was thinking to put up chicken wire and divide the coop (which holds 9 chickens sufficiently) so the ducks are separated. Advice?
