I'm glad you are here too, LJ! It helps to have someone with similar interests to bounce ideas off of and see what comes back. Helps me think and then formulate my thoughts into action. I've only been intentionally improving pasture for the past 7 yrs or so for the purpose of livestock feed but it makes a lot of sense to me to use that green stuff out there as free food that I don't have to buy. I had to go a long way to keep my mother, the mowing queen, from cutting the grass too often or too short so as to let the grasses go to seed and reseed themselves these past two years.
At my place, I just kept sheep on the grass and didn't have to worry about mowing, letting the sheep condition the pasture in a more natural way...all the while fertilizing it as they went along.
You are well ahead of me in active poultry pasture management! Your practice experience is a great resource.
Have you planted comfrey? I keep reading good stuff about it, but this resource says it is partially hype ... http://www.feedipedia.org/node/92
It regenerates well, but isn't as digestible or high in protein as white clover.
