Compost piles

I have managed to create some compost in the bin on the right. it only happened in the middle of the pile so I clearly didn't turn the pile enough - ok at all...the bin on the left was a total failure, as well as the one in the middle. so I consolidated the two into the middle pile which needs more green matter in order to break down, and have turned the pile on the right, and told myself that I will do it again soon (we'll see).
