A laying hen reaches maturity and begins laying eggs at around 4-6 months of age. She will lay an average of two eggs every three days for the next 3-5 years. After that, you may wish to consider adding the girl to the stewpot. Laying hens are not as tender as young meat birds (which are typically slaughtered at eight weeks of age) but their meat is still salvageable if boiled or tenderized with some vinegar prior to cooking.
