Hello all, I am trying to figure out what to expect or how to prepare my greenhouse this coming season. I live in a zone 3-4 area and have been housing 44 chickens in my catapilar green house all winter(about 5 months so far). My original idea was to do this to boost the fertility, keep weeds down, and to lower the slug population throughout the winter months. Come about May i was hoping to start my tomatoes and such in there.. My main concern is how good my soil is really going to be in there with all the poop everywhere? Is it going to be safe for plants? Will it burn or prevent growth? I know chicken dropping are pretty potent, but my hope was they will be scratching away excellerating the breakdown process and essentially tilling and readying it for this years planting. I will add that fertility to start in there was low to moderate at best. How much time do i need before planting? Should I scrape the top layer off, or should i just till everything in? Any thoughts will be much appreciated.
