My hens are going into their 2nd year of egg laying. I've heard that hens start slowing down a lot in their 3rd or 4th year. I don't want to keep hens that have cut their egg laying by about 1/2 when that time occurs. What do you do with your hens that are 4 years old or so? At first I thought about butchering them and using them for chicken and noodle chickens, but I'm wondering if they might be to tough for even that when they are 4 years old.
