ok heres the situation. right now i have my 16 chickens and 4 ducks free ranging during the day and in my coop at night. (my coop is 16ft by 16ft) i was planning to add 10 more ducks, and i have to take 12 more chickens from someone who is moving away. would my coop have enough space for the soon-to-be 42 birds to be at during the night. (i think it would because my soon-to-be 28 chickens would be on their perch at night) also would it be ok for 40 of the 42 birds to be locked in the coop together for 1 day or two if i was on a vacation. (two of my birds can fly out of the coop)
