My five hens are about 2 1/2 years old and I've gone from about 3-5 eggs a day to about 2 a day. I've read that hens peak in egg production at about 2 years. I'm wondering if they've hit their peak or if it's just a matter of the heat we've been having. If they have peaked then I guess I'll need to consider when to start rearing the replacement flock. I have two daughters, 12 and 14, so I'll need to figure out how to handle the "replacement" part.
