So, the chickens have been in their run for about two months now, during which time they have (predictably) reduced it to bare earth. We are fortunate enough to be obligated to be somewhere else for my parents's jobs in the summer, so someone with a large flock of chickens is going to take care of them in our absence. My point is, the chickens will be absent from their run for around 2.5 months. We would love to plant something in their run then, preferably a big, fast-growing weed, so they could have some fun when they get back. Yes, we have some grass seed, but all we are looking for it some vegetation to cover the ground, and the grass doesn't go fast enough. I've read about people using rape seed, etc, but I don't know where to get that... So, any ideas for a weed? We'd have so be able to find it somewhere around central VA or be able to get seeds in seed packets. Thanks in advance!!
