Since August our chickens have laid in the nesting box. We obviously saw a decrease in production over the winter.we've had a couple of days with 2 eggs, but yesterday and today, nothing. The problem is, yesterday I heard an egg song being sung, and today I went out to check and there was a chicken in the nesting box, nesting. But 3 hours later, no egg. Where are some common places to look for eggs? They free range around a quarter of an acre, with a lot of boxwoods.
