Hi everyone, greetings from Sydney Australia. In September we bought 4, 16 week old Isa Browns, all of whom are very well and happy and we started getting eggs at the end of October. Unfortunately, we've only ever had 3 eggs a day, and have managed to identify one hen as never laying. Is it possible she's just a bit slow, or does she need treatment? I'd very much appreciate your help. Of course, we're in mid summer now so it's not because she's cold!
