On a very small scale, I currently have an acre of grass that's taller than me, I daren't let them loose on it as they will a) stuff themselves, b) trash it and c) eat the nice bits to the ground and leave the less nice bits which in this drought (still no rain here) will stress it even more, so I was wondering if there is any reason not to make hay, just cut a bit by hand and turn it a couple of times before feeding it?
