The rye is annual rye grass, not rye grain. It will not have the coarse stems of the cereal ryes, but be more like the stems of a tall fescue or thimothy. The grass will not start stemming until around April. I chose this type of grass because it is fast growing, has a very fiberous root system, and if not allowed to seed, will not grow past about June so as to not pose a weed problem in my garden spot. What the chickens dont eat will be plowed under as a green manure around the first of April in time to prep soil for a veggie crop.
This is a chicken forum so I wont get into detail about the soil fertility issue, my main concern is how will this much grass effect the chickens if injested as free range feed. So far it it seems everybody is infavor of pastureing the birds on this feed source. If no-one has different opinons of this subject, I will consider the rye a safe food source and build the fence to hold the chickens.
