I am wondering when I should replace my laying hens.
They were hatched in the Spring of 2011. I have 25 hens that are consistantly laying 12 to 14 eggs a day. Since it is winter I think they are doing fine with that amount. Last summer, they were laying from 18 to 23 eggs per day. I do plan to add another 25 chickens next Spring but am wondering how long I keep the older ones.
