My one and only Welsummer started laying very small eggs in August and kept laying very small eggs till about the end of September. Then she just plain quit and hasn't laid one since. We are keeping the light in the coop at about 15 hours, so she should never have quit. Any ideas?
She may be in molt. They will stop laying then. If there are feathers anywhere, and if she's looking a little thin, then she's in molt.
