I have a flock of hens, 5 buff orpingtons, 5 barred rocks, and 6 silver laced wyandottes. In the spring they will be two years old. I purposely did not get a rooster because my neighbors are a bit close and I didn't want to generate any noise complaints. So now I'm thinking I want to "borrow" a rooster for a little while. I'd like to replenish the flock and watch my hens raise some young. My questions are: Is borrowing a rooster a good idea? *Should I worry about the flock accepting him? *Should I worry about introducing disease? When is the best time to bring him over? (I'm guessing mid spring, I live in eastern PA and it can be pretty cold in March and April) How long should he stay? I only want 8 or so healthy hens out of this in the end. Thanks for your advice!
