We had a flock of hens where each hen would lay an egg everyday. After a while, we added a rooster to the flock, and they stopped laying eggs. We figured it was the rooster, so we gave the rooster to our neighbor. We waited, but they never started laying eggs. They're 3 years old. So do you think it was the rooster that made them stop laying or their age? Because we thought that if it had been there age, they wouldn't off stopped so abruptly. We are confused..
