We are right on the edge of keeping the bananas alive. Zone 9a. It was an experiment that is going well. Learning about microclimates and such.
A lot of people keep birds for the eggs. I wanted poop. Sorry Kiki. Poop for the compost is working amazing. After the compost ages, I open it to the chickens and they disassemble the pile. Makes it easier to pick up. Feed bill drops drastically during the few weeks they are chewing the pile down. Bugs, microfauna, worms and such.
They have to stop eating my cucumbers though. And tomatoes, lettuce, radishes...
