I have had a couple pullets increase in volume quite a lot in the last couple of weeks, and I was worried what they would sound like when they're ready to lay. I found out today! It was more like screaming than the egg song. I'm illegal in the city, so I'm really trying to keep the noise to a minimum. If I get rid of the two loudest ones, will another one take over the job, like roosters do? I'm not sure if I should blame it on individual behavior, or chicken hierarchy. Just curious before I pack them up and send them to the country.
