Does anyone have experience with birds using multiple coops?? Since I have 2 extra chickens, I am not meeting the standard requirements for space in my coop. Its not been a problem so far but I am concerned about what will happen in winter. I can't build a bigger coop overall but I could build another elevated coop in my run that would be good for 2-3 birds. My question is--does anyone have experience with using 2 coops?? Will the girls use both or will they all go to the same home each night?
