I would start by improving the drainage in some way, perhaps a drain pipe running through and out to a lower area. I ended up building a pond on my last property because it had terrible drainage and was a soupy mess.
Next, what type of dirt do you have? If it's clay, then adding sand, gravel to it is a great idea. On top of the pea gravel, you can add wood stove pellets. They act like sponges and soak up water quickly, assuming you use enough.
I had horrible clay, poor drainage and nothing growing on my last property. After installing a pond and spreading horse manure everywhere, limestone/gravel for walkways, I finally was able to get plenty of grass growing, Bermuda with winter oats for the winter time. Of course, won't work for your chicken coop but did work in my cattle and horse pens, other then the heavy traffic areas.
