Frank's single privacy sulky perches with roofs
These are the famous Frank's single privacy sulky perches withe roofs. Most greater pet shops in Germany offers them. I have about 30 perches in my outdoor aviary. During sundown all Fifes sit on the perches without any rumble. The distance between two perches is 10 cm, that is enough for Fifes.
The perches are very easy to clean. Only hot water and vinegard and they are really new;-)
