reading this with real interest as it's just moved into the rainy season here in Scotland. (the rainy season basically means August till June here) and my clay soil garden has already turned into one great big swamp. I've dug over and turned the 'grass' so some of the standing water and sludge can drain and aerate the soil as it's so clay thick even the worms dont live there anymore. I let my chicks free range from about 7am till it gets dark, but they have a good sized coop with an attached 2 metre fenced run to themselves at night. It's turned into a complete mud bath, chickens squishing about in nasty muck. I tried putting sand down before but it just washed away or stayed as wet sand, less muddy, but every bit as squishy as before. Half the run is covered with tarp for shelter from the sun/rain but the other half is open caged. I have no way of increasing drainage to the site as it's a small flat enclosed grass garden (5mtrx5mtr) with high fencing all round. Would woodchip be more likely to stay put and dryish than sand in that sort of closed run? I dont really want to tarp the lot as they need some daylight, lord knows we get precious little in the winter here as it is.
