My chickens are 2 years old and they will go lay in the nesting boxes for about an hour each day just to leave without laying an egg. My 2 eatser Eggers are still laying perfectly normal getting 1-2 eggs a day from them. I maybe get 1-2 eggs a week from 2 Rhode Island reds and 2 barred rocks combined. They’ve had bald backs and no tails for over a year now so it’s hard to tell if they’re molting but could that be the issue or is it something else?
