I tried to side dress my blueberry bushes and fig trees with compost, then mulch with some chopped up leaves. When I checked back after a few days, it was all gone! I think the chickens are scratching in it and send it all into the grass or another chicken dimension. Is there a way, other than a fence, to get the mulch and fertilizer to stay put? I would really like the plants to grow better this year but don't have the time/money to construct a fence. Could I lay down some chicken wire on the ground over the compost? I have some left over from building the run.
