Yes, I don't have any sort of wood or anything holding my garden beds in, they have always just been rectangular piles of droppings, hay, straw, lime, and dirt on the ground. I've been happy with it, because anything permanent detracts from my laziness and spontenaity. I can change things anytime I want. Scratching back the layer of straw when you're ready for planting sounds like a fine idea. That probably prevents the nutrients of the soil from disappearing up into the air with the sun and the wind. Something I should start doing. The nitrogen from chicken poop never seemed to prevent any fruits or vegetables from forming that I ever saw. I believe ducks have a teensy bit more nitrogen in their droppings, but I've planned accordingly by having less ducks than I did chickens, and more room for them to run around. Plus the neighborhood dog walkers constantly commented that I was being cruel somehow by keeping my chickens in cages. They didn't quite understand that there was only a couple birds in each cage, and I had payed close attention to their space requirements, and they probably didn't consider the unbelievably close living quarters that the producers of their own store bought eggs had to live in! Once the animal control even got called on me, and when I showed him my flock, he laughed, got back in his car and drove away. Not that I'm doing any of this to please others, but less flack would be nice. A good thing about poultry dropping as opposed to horse manure is, (so I've read, and life often shows me that what I read could be totally wrong) that horse manure can have a lot of salts, overwhelming the soil after a while, and bird droppings are supposed to be richer in useful nutrients too. But I'm sure in a little home garden with low demand (as opposed to fields farmed to their maximum output), the salts wouldn't really be a problem. Maybe with very alkaline soil you might not need the lime, who knows. You could just plant one bed that has lime, then another bed that had none. I always threw lots of alfalfa on the ground of the chicken tractor, a layer every few days, and that gave them something to peck at, push around, and also it absorbed the excesses of nitrogen and what-not and things weren't stinky. So by the time I moved the tractor to it's new location, half the garden bed was already there waiting for me, shaped up tight by the tractors perimeter. With ducks I won't have that really, I think I'll just make a path straight into each duck-prepped section with a cirlcle shaped "keyhole", I guess they call it, at the end of the path, and plant all around the path and the keyhole. My sections are going to be oblong anyway. I'll put stepping stones here and there so I can reach far away things, so I don't squish down my beautiful soil walking here and there. The green manure idea I like too, and I kind of wondered about planting some kind of crop like flax or I don't know, haven't researched that one yet, that they could enjoy munching on by the time they got there, or that I could harvest on occasion to give them food and save myself some money on feed and driving to get the feed (currently a 40 minute drive). If that crop were leguminous, yeah, it would also make a nice green growth. Yay! I'll probably be posting my adventures. As you can see, I'm a little, uh, obsessed?
