She's only about a year and a half old. She used to be a consistent layer, about every other day. Then before she stopped laying, she was laying only soft shell eggs. She eats very well, acting mostly normal. Sometimes she seems a little sleepy when the rest are active, but I've only noticed that a few times. She always has an excellent appetite. She is getting pretty thin though.Without any supporting information that could give us some clues, such as age and laying history and behavior of late, the egg could be a result of poor diet, old age, young age, molt or disease.
What all and how exactly are you feeding?She always has an excellent appetite.
