Ok another question, my chicken run is devoid of any vegetation, its just mud, and it looks horrible and makes the chickens feet filthy. The inside of the coop is very clean and Id love the outside to look a little less like a refugee camp. My two thoughts were to either use sand or use pea stone/gravel. Im not sure where I can get sand around here but I can get a ton of the stone for like $10. Id rather use the stone because I think it would look better but are my chickens going to gorge themselves on the stones. I know theyd eat a lot of the smaller stones as grit but will they try and eat too big of rocks. Its ok if they eat some Id add enough that it wouldnt matter much, so the question is would it be safe for my hens.
