Every day for the rest of their and your lives, except maybe a week of the year, something is either eating your eggs, or they need more protien feeding, and possibly worming. My pekins made a nest in there hay stack in there pen, after they do there morning laying they get the door opened to come out and play, I hatched in incubators over 300 eggs last year, sold eggs to the Asian clients that do nails etc., and ebayed eggs, and scrambled eggs, and fed the dogs and pigs eggs, oh sweet jesus, there is only so much you can do with so many eggs, fertility was great with 15 hens and 3 drakes, I have pictures on website. Are you sure you have a hen? Pekin are prolific layers.
