I got a standard size chicken and four babies from a lady I work with. We had discussed the rooster next door. Well she mentioned after we have everybody at home that, when the babies get old enough to get out of the brooder that they might go visit the rooster. There is about and acre size lot between us and him. I'm worried they might go and not come back. I don't want to have to keep them penned all the time. Could this really happen? Should I be worried?
