I have 3 chickens that are 15ish weeks old. I have been letting them out in the yard with my 2 dogs since the chickens were 10 weeks old, sometimes supervised and sometimes not so much. So far, the dogs are not bothering the chickens or showing interest in them at all. They will, however, sneak into the coop and eat up all the chicken food. One is a golden retriever and one is a greyhound. Should I just figure that since they haven't eaten them yet, they aren't interested?
