Our 2 year old Americana has been laying eggs for the last 2 weeks that are a bit bumpy/rough and thin shelled at the top. The other 14 hens are laying eggs with nice thick shells. She lays blue eggs and the coloring has been a little darker at the top too. We feed sunrise organic layer feed and always have oyster shells free choice. She came back into laying about a month ago and all was fine until 2 weeks ago. The flock shows no signs of infectious bronchitis. What do you think the issue could be?
