We have a hen house which attaches to a run. Our girls free range most of the time but when the garden needs a "break" from the poo and the digging or if the weather is very bad, we keep the girls in the run. At first the "floor" of the run was grass, which of course lasted about a week. Then it was just dirt/soil but this became yucky pretty quickly. We read about using pebbles as flooring so we bought numerous bags of that and laid it down. It seemed to work well at first but we didn't get the right kind and I think it was a bit sharp on their feet (no injuries, just didnt seem comfortable). We were thinking of removing the old pebbles and getting some new nice round pebbles for the floor of the run but having read a few posts here I'm wondering if that is the best option. I read about using sand but wasn't quite sure if that was meant for the floor of the run or just the hen house? What does everyone else think is best? Thank you.
