Ok having trouble. Have had problems with a chicken, or chickens, pooping on top of the nesting boxes. I tried to put a huge plastic garbage bag up there and secured it with push pins, but that chicken pecked it undone. So. Then I used OSB as a solution and blocked off the top of the boxes. So check this out... Now she, or they, are mopping inside the nest box. These that are doing this are not fully mature, but will be laying shortly.. Probably within a month or so. I have others who are laying though... Ok... So how do I stop this behavior?? Can't jut close off the boxes... Then my other birds can't lay... HELP!!!!!
