Well after having fun raising the Silkie chicks to egg layers and one dying, I decided it was time to find a new home for the one remaining chook.
Now im not sure if they do ok, but I dont think anyone wants to live alone on a balcony 28 floors up so decided to adopt her out to a new home.
She is now living in the countryside with many other Chooks and enjoying more space to peck around in.
It was a fun experiment and proved you can keep chooks in a small space with no smell.
The reality is the production isnt worth the time and effort needed.
I would rather put the time into another aquaponics setup with edible fish.
