This discussion is very helpful, thank you everyone!Even a shallow scrape around the uphill side of the coop and down the sides could help.
Building up the ground inside the coop with plenty of dry organic material will also help.
I have a narrow stone path either side of the run, just stones and blocks laid on top of the soil, and if even a shallow scrape would help then I could scrape out and lay rubble or pebbles under the paths. That would solve the problem of space in the garden.
Building up the ground inside the coop - such as making ramps - would still be helpful for the times when the water can't drain away because the ground all around is waterlogged.
