We live in MA and we had two feet of snow (we shoveled the pen a little) and then it rained all last night. This morning the run is a slushy, muddy, so stinky mess. What should I do? It really smells bad which is why I'm concerned I guess - it seems unsanitary for them. I was thinking my two choices are to shovel out the whole pen so it has a better chance of draining or putting down gravel.
