Gosh, it's been 19 years since I was pregnant with my daughter... but I remember being exhausted and sleepy before I found out.True, but what kicks off egg production is hormonal. I'm more concerned about the actual process of creating eggs. That takes energy, and while in CT we don't always have cold winters, but they can be wet winters... which means you need more energy in heat to keep warm. Just like baking a baby for mammals takes energy, fats etc to create... If they're hormones and bodies tell them to make eggs, then I'll enjoy them... if not, then I'm not really going to be upset either.
@bobbi-j your stories emphasize how different situations can get and having the need sometimes to do what you might not others. And how flock dynamics (predator attacks/illness) can effect things. Also that chickens don't know the rules about when they SHOULD start laying. Guess you can't count you chickens before they hatch but don't count your eggs before their laid either. And honestly even after your chickens hatch your count might be thrown off by predators...
