I bought a batch of assorted pullets all between 2-3 months of age, at the end of April. All are laying well except for one EE. I estimate she is at least 36 weeks old. They are in a large run with no egg hiding places. We got our first frost last night; is it possible she will not lay until spring? Or never? She does seem to be at the bottom of the pecking order and is pretty skittish. Could this also be contributing?
