We had him free ranging in our fenced back yard and thought he would go back to the run to sleep when it got dark. Well we went out at dusk and he was nowhere to be seen. We had him seperated from the other two in his flock because he was fighting with another rooster. I really don't think anything got him, we saw him just a half hour before. He flies pretty well and we figure he's gotten up in a tree or something. Do you think he'll come back tomorrow for food? Do chickens have a homing instinct? Or do they just take off? Our daughter is kind of upset. We left the run open with water for him.
