We are finishing our coop this week and will begin the enclosed run next. Is there any hope of keeping forage grasses growing in there for them, or should I just give up the idea and embrace the moonscape to be? It will be about 16 - 20 square feet per bird. I will be pasturing them in another area with nearly 150 sq per bird (I have 3 areas with that much space so they will move every couple of weeks). The enclosed run is mainly for winter and for those days when I am not able to be around to pasture them (we live in an area with high predation). Second question: what grasses/clover/greens grow best and fastest for them? We have a lot of clover here, it seems to do really well, but can they get too much of any one green? What do you plant in the pasture area for a chicken? Third question: we are battling the virginia creeper, poison ivy, and poison oak, that lives in the newly cleared areas of the pasture. They do a number on my DH and I, but are these hazardous to the chickens?
