Coping with uneven pasture growth

Chickens in lush grass

This spring, the grass in our chicken pastures was growing faster than the flock could eat it.  As a result, I left the chickens in each paddock a long time to eat all that lush greenery, and by the time the girls got done with all three paddocks, the earliest grazed paddock had gone to seed.  That depressed our summer growth extraordinarily, resulting in over-grazed pastures all through the summer and fall, despite the fact that (on paper) our pasture sizes seemed more than adequate to handle the chickens living there.

This problem is very common in improperly managed, rotational grazing settings.  Bill Murphy suggests three ways to deal with lush spring grazing:

Set aside the excess spring pasture and cut it for hay.  On a large scale, you can simply keep the livestock out of several paddocks and then go through with the tractor to cut hay (preferably when the grass is no more than 10 to 12 inches tall so that it doesn't shade out legumes and slow regrowth.)  I suspect that on the backyard scale, cutting our small chicken pastures with the ninja blade or a scythe would be relatively painless.

Graze more animals in the spring.  We got a late start with our broilers this year, but if we'd had a bunch of hungry young beaks to fill when the pasture was growing like gang-busters, we could have used up the excess pasture that way.

Mow behind animals.  If you simply let your animals graze the lushest part of the pasture and rotate them at six days despite lots of plant matter being left, you can come in behind the animals and mow.  This is the most wasteful and labor intensive, but with a bagging mower you could be collecting those high nitrogen clippings for the garden.


Stockpiled pastureAssuming we get the spring overflow figured out, what do we do about the summer and fall slowdown?  The solution is to have more paddocks.  With our recovery period estimated to be 44 days in October and the maximum occupation period being 6 days, we'd need 9 paddocks to keep from grazing each area too soon.  Although that sounds tricky, I suspect that we could subdivide our existing pastures into much smaller sections using temporary fencing, perhaps using pathways created by a hoop of remesh to lead the chickens to each area at the proper time.

Of course winter is another matter entirely.  Bill Murphy recommends stockpiling summer growth to feed your livestock in winter, but non-ruminants won't get much out of dried grass.  We'll continue to experiment with annual grains, and will have to get creative if the pastures look bare in midwinter.

Our chicken waterer gives the flock something to do even if they run out of bugs.

There is an amazing board game called Agricola that simulates managing a farm. It is a top-rated game for complexity, actually...and I could never understand why "building paddocks" was something a player could invest resources in doing...now I have a wee insight into the whole pasture management viz a viz choice and number of livestock. Who needs TV when there is much to learn just to manage 50 acres? God, we city people waste our lives...

I adore Agricola --- it's my favorite board game. I'm always amazed at how many permaculture concepts they manage to work into a very playable game.

Of course, the way I homestead seeps through into the way I play the game, so you can often beat me by understanding my Achilles heel --- I don't believe in big houses, etc. It does help me get big livestock dreams out of my system without having to cut down trees here on the real farm. :-)
