I have 3 younger hens, 2 of which are for sure laying. I have 2 14X14 boxes in the coop with straw, plus a dirt floor and plenty of straw for make your own nesting. They have been laying in one box and I counted 22 eggs the other day. yesterday, 2 of the girls were in the other box at the same time even. And there are 4 eggs in there now. Its like the first box may have been abandoned.. I thought one would start sitting soon but apparently not. Should I be concerned about the first eggs? We are getting into the upper 30s some nights although 40s is more common.
