I have eleven chickens total: 7 hens, two of whom are currently molting, two who have already molted, and three who are laying sporadically due to the season. Then I have 4 Welsummers who are 30 weeks. Only one of them is laying and she has been laying regularly about 4 eggs a week for the last month. Yesterday and today, I found a shell-less egg in one of the nest boxes. When hens who have molted return to laying, does it take them a while to start again? Could these eggs be from one of those two? or is it possible I have another Welsummer beginning to lay and she just hasn't figured things out yet?
