I have a 16ft long by 8ft wide and 7ft high fully enclosed run for my chickens. There is also a section that goes under the roost itself that is about 6ft deep and 18in high. We have 7 hens and a rooster that use this. The problem I am running into is with the ground of the run itself. Obviously the chicks have eaten every bit of the grass from the run. We do let them graze outside of the run some. The problem I am having is that it is so muddy in the run. I recently moved the water and feeder to the run door so that I could get to them easier. The ground in the run is ever so slightly sloped but still does not provide any run off of water. I have literally seen pig pens less muddy than it is in there . It makes it next to impossible to get into the run and do anything with the chickens right now. We tried spreading some hey and that worked for a bit but seemed to only make it worse after the hey started mixing in with the mud. I could keep adding hey and such but that would get pricey in the long run. Luckily I thought ahead when building the coop and run and can access the layer boxes from a door on the outside of the coop so I don't "need" to get into the run often. We do like to get in with the girls though and hang out with them. Not so much now during the winter months but definitely in the summer. So I guess my long winded question is, what do others do to prevent the muddy ground in the run during the winter wet months or is there even anything we can do? To give a perspective, there is currently about 1.5 to 2 inches of extremely slick mud in the run right now.
