Our two red star hens, Abby and Penny, have stopped laying for some reason! We don't know how old they are, but they seem pretty old. They have been laying large-X large eggs until the past weeks. There have been no major changes lately. Now, only our young hen is laying. Here's some info about them: age: unknown(may be pretty old) gender: both females weight: unknown height: unknown usual eggs size/color: light brown, large to X-large stopped laying: few weeks ago any physical issues: Scaly leg mites Penny: Sneezing past weeks, not as much now. Color of hens: light brown and white Breed: Red Star(maybe mixed with bantam?) Shape of hens: Short legs, small body, looks normal but just smaller than usual Coop conditions: fairly good Nest boxes: Yes. 3 neat boxes. Food: Laying mash and cracked corn, all natural Water: always available eggs have been normal when they were laying(no bumps, odd shapes/sizes, etc...) Sorry, no pictures. Does anyone have any idea about why they haven't been laying??? Thanks!
