I've recently noticed that my free-ranging White Leghorn seems considerably leaner than her five sisters which include 2 Reds, a Sussex, an Orpington, and a Barred Rock, all of which are 1 - 1 1/2 years of age.. And I'm wondering if the Leghorn is just naturally a slimmer hen than the other breeds, or if something else may be affecting her. I will admit that she eats more than any of the others and that she is at the always available feeder more frequently during the day than any of the others. And although she has regularly laid five eggs a week, of late her production has dropped off considerably. Otherwise she seems happy and healthy and assimilates with her sisters nicely throughout their daily activities. Any thoughts would be welcomed.
