My Easter egger hen is 2.5 years old and has been laying relatively consistently since she was 6 months old. I got her when she was a couple days old so she’s been with me almost her whole life. She’s never had any egg issues. I have crushed oyster shell that they seem to go through extremely slowly (if at all). She got a respiratory virus about a month and a half ago and stopped laying. She has since recovered and is acting all normal. She laid her first egg again maybe 5 days ago. It was normal looking, normal thickness and in the nesting box. The next day, she started laying paper thin eggs. I’m back now and it hasn’t changed. She used to only lay in the nesting box, but I’m finding papery egg shells in random places of the coop. Almost like she lays during her sleep and then steps on it when she’s leaving the sleeping area. It felt the texture and it’s not a normal texture. Nothing in her life has changed recently. What is going on?? She has the same access to her oyster shells that she always has had.
