I'm not sure we an issue or not. One of our hens was laying an egg every other day (1.5y Wyandotte, in cold cold mi weather), and now she is not. I have also seen her stretch her head all the way up and put her head back with her beak open, twice. I felt her neck/throat and didn't notice anything. She's eating and otherwise acting normal. No eggs from her for 1.5-2 weeks. Thoughts?
