I have a one and a half year old Aracauna that hasn't laid an egg in over a month. She's not hiding them, she's not broody, she's looks and acts just like the rest. She's very active and alert. She was a great layer, but stopped over the winter. She then started up again in Feb/March, but just stopped cold over the past few weeks. My other 2 hens are laying regularly. This is my only easter egger, so she's the only one with blue/green eggs. I've been keeping them penned up to make sure she's not hiding them. Any ideas?
