Hi Backyard Chicken folks I have raised chickens off and on for 8 years. Absolutely made mistakes but have enjoyed caring for and owning chickens the whole time. As to those mistakes Two years ago we lost the whole of them from an attack by a neighbors lab. We lost one from a hawk attack and generally learned we can't have smaller chickens and rehomed our beautiful silkies. Last year we lost half of our chickens to a fox that lives on the property. Behind some lillies (that blocked the growing weakness visually) a corner of the hen house, a converted work house from the 30s, was a bit of decay. We have a fox that lives on the property and she figured it out before we did and scratched her way in. We have had the good fortune of having fertile eggs and a local chicken expert was kind enough to incumbate them for us. We now have 4 babies running around the chicken yard. Now we lost one of our two year old hens to an illness. We called vector control, and California US agriculture. We were hoping to find out why she died. Vector said they were not interested. And the Ag department has not called back yet. Predators are a way of life and although we are willing to wire the chicken house and a run we want them to free range and we are not about to trap or kill the hawks or the fox. Keeping them locked up at night, not letting them out until they are full sized and only having full sized chickens...are where we have drawn the line. Now it seems we have a new predatory and I am not sure what to think about how it got there and what it is and how I prevent it. I am in Sonoma county and open to feedback and a chance to learn so that I can be a better care taker of my little flock. I am want them to live healthy long lives. I have not given any shots until now. There hutch is well ventilated, they have access to a run and are let out to free range most days. They have clean water and organic food from the feed store daily.
