We are rather new to chickens, because we are plant people. I got the chickens for the poo, but the eggs are nice. (I use my litter waste for my garden. I value it highly.) We collect oak leaves all spring to mulch the many gardens that we have. We have always more piles of leaves than time to spread them all. Last weekend hubby carted a wheelbarrow full of leaves into the run. One lucky girl pulled out a huge earth worm and they dove into that pile like it was ...full of earthworms. Anyway, each day he gives them a pile of leaves. It keeps them entertained if nothing else, and their run has a nice mulched look about it. Can I just give them all of my mulch pile and I'll use the new leaves for my garden? Can I try to get a deep mulch for their run? Is there any danger to a deep mulch run? ...as long as it is not always wet? Do any of you see any harm to this? It is a very large run (24x36)and we plan to make two more runs with the idea that once they remove the Bahaia grass rhizomes, insects, weed seeds, and fertilize it for me, then each year I can rotate my new garden to last years run. as long as I do not use any non organic pesticides, would that be safe for them? and then let them into the old garden to till it for me? would that work? am I asking for parasites? disease? Thanks so much!
