Geoff Lawton’s recent chicken tractor on steroids
video. I like the idea that the ecological benefit of chickens can be increased with a few smart tweeks.
I’m planning on a 2 paddocks in their main run + a walled coop for the evening/protection + almost free ranging (paddock shifting around the property) + chicken tractoring/compost making. You might not have enough space for all that.
But…the design you provided could be enhanced by dividing the run into two and loading one up with leaves/grass/whatnots to increase insect and worm development.
Might have to bring down the number of chicks to do that or raise the space of the run.
I’m a newbie too. Planning to get some in May, doing a lot of pre-chicken-arrival work now.
