LOL - I still manage to hurt myself in the run from time to time. It's a hoop coop style run and there is plenty of clearance in the center, but step a few steps to either side and stand straight up you get a fast reminder of how tall you are (especially since I somehow manage to ONLY do it when standing directly in line with a hog ring!)x2 I had the same issue. Doing exactly what Ole Grey Mare suggested made a difference. I don't mind the litter from the coop being dragged or scratched from the coop into the run, since they are both on bare soil with deep litter over that. But it was a PITA to keep the litter from ending up on the yard from the people door. So we put a piece of wood there to hold it in, making the doorway a little higher than it was originally. Um, however, I should point out that it took me tripping about 5 times to finally remember that it was there and to pick my feet up higher when I gathered eggs. <sigh>
