Last week my hubby and I built a wonderful predator-proof (completely encased with hardware cloth) chicken house and pen, and the chickens are all moved in and happy. I would like to also keep a few budgies or cockatiels in it - they would live in the upper airspace and the chickens on the floor for the most part. But I have a few questions: 1. Weather/Climate: We live at the North end of San Francisco Bay in middle California. We generally have a mild 4-season climate with some hard freezing between mid-December and early February (though it varies from year to year). Does anyone know if any small cage birds, such as parakeets or cockatiels, can live outdoors in this type of climate? 2. Are chickens compatible with small cage birds, in termsof behavior and health? Or will one harass and kill the other, or spread diseases? Thanks for any help I can get on these subjects!
