An update on my attempts to put into practice Geoff Lawton's "chicken
tractor on steroids". I'm still not 'there' but I'm definitely on the way. During our Winter the chickens have been housed in one or both of our tunnel houses with extra area outside. The outside area is moveable so that they never run out of green grass/weeds to graze on. I've been making compost in the tunnel houses. Each week I start a new heap with some fresh manure collected from elsewhere on the farm; cow, sheep, donkey and/or guinea pig. House or garden scraps are added each day as well as any slugs and snails that are collected from the garden. Because the volumes are lower than in Geoff's system, (because we have fewer chickens), I've been combining the heaps so that I get one heap about every three weeks that is big enough to heat up.
They've also been getting sprouted wheat. I previously fed sprouted wheat and got NO eggs but within a week of feeding pellets they were laying. However, this year we've been getting a few eggs right through winter from some pullets and now that day length is increasing, (I'm in New Zealand), the older ones are joining in with more eggs each day. So, I'm satisfied that they are getting enough protein. I consider that to be the major hurdle to cutting out bought feed. Even if this was all I achieved our feed costs would be dramatically cut and their would be no unsustainable, imported portion in their feed.
But I'm not satisfied!
As we get into Spring and Summer there will be more and more garden 'waste' available and I'm able to get cafe scraps between October and January. So, I'm hopeful that I can wean the chickens off bought feed altogether. Also, last year I built up my worm beds so I'm hoping that this year I'll be able to expand further and have spare to feed to chickens and ducks.
I've been working a similar system with the ducks and they are also beginning to lay. They are in a fixed pen which includes a
pond. There is always grass growing in the pen but I think I will
sell some to reduce the numbers anyway, (from about 23 down to 8-10) so that grass can become a bigger portion of their diet. Their are some large New Zealand
flax bushes in the duck pen. I've been piling up the dead leaves which, if left about a week, seem to attract good numbers of worms. Each morning I just turn a layer off the pile to form a new pile. This exposes worms which the ducks snap up in the twinkling of an eye.
