I have 4 chickens, 28 weeks old. I have 2 buff orpingtons and 2 speckled sussex. Five weeks ago, a buff orpington layed the first egg. A few hours later, another egg which I assumed was from the other buff. I now consistently get one egg a day, sometimes in the morning, sometimes in the afternoon. I have only seen one of the buffs lay for sure. According to my thinking, if I had 2 hens laying, there would be days I get one egg, days I get 2 eggs and maybe a day here or there when I get none. No, it's always one egg a day. So what do you think? Do I have one hen laying or two hens? Could one hen have layed the first and second egg in the same day? And when might I expect the sussex to start? The nights are getting cooler here, down in the 30s, days still in the 50s. Could the sussex possibly wait until spring?
