Hi I am fairly new to having chickens. I have had my pretty girls less then a year RIRS. A few months ago I added some more that I bought out of the local paper. Barred Rocks hens, 2 roos one a leghorn and one a leghorn RIR cross. As well as a Leghorn hen that was so tiny with a broken foot, I just couldn't help but take her home too. They are all doing well and I am very surprised at how friendly the roos are. But I have been having a reoccurring problem with their dirt floor run. Every time it rains hard or the snow thaws, it's terribly muddy. I feel just awphel for them. I Have tried adding gravel and even resorted to spredding straw around when I think it is just too bad. I have been told numerous things at the local feed store to use, everything from the grave to crushed corn cobs. And I just have no idea whats best. Any suggestions would be greatly appreciated.
