I have a run area attached to my coop. I live in Florida so it is pretty much always wet here. I am having trouble keeping the floor clean for my girls. I first had a dirt floor in the run but it would just get muddy and mix with poop then harden. Yuck. I was digging it out but I would eventually reach China. Then I tried pea gravel and sand. Pretty much the same thing happend just with rocks. Lastly I tried drainage rocks and sand....still not too good. We have had ALOT of rain. What do you think? More rock? More sand? Or do you think just pour concrete and put pine shaving on it?? HELP! I don't want my girls to get sick from having wet feet all the time! THANK YOU!!
